Wanted "RARE" 1967 Corvette Convertible "BB" L36,M21,G81, and N11.
I'm the original owner of early built (September 09 1966) "St Louis Body" 1967 Corvette Convertible VIN 194677S100560.
As you can see the Corvette was 560 built for 1967 Corvette model year and trim plate state an "S" for St Louis in lieu of an "A" for AO Smith division of Dow.
I have been looking for this Corvette for many years.
Corvette was a rare factory built RPON11 (OFF ROAD SERVICE ASSY) car.
I may not see this Corvette again but asking for anyone's help to locate Corvette.
This Corvette was ordered my me and my father July 1966 and was a "Class A" GM discounted Corvette.
The Corvette can be seen on lost 1967 Corvette registry.
I have the original bill of sale, protect O plate, and extra set of original keys.
The manifest "So called tank sticker" was left on the tank and the extra copy of manifest stuffed under dash right side of steering wheel.
It was a mistake selling Corvette and leaving extra manifest document under the dash.
These are the original options ordered on this 1967 Corvette 19467 style convertible.
This write up is real and not a joke.
Looking for help locating Corvette 560.
I'll surrender the paper work, protect o plate and keys to the owner for a picture of Corvette showing the trim plates on the tie bar just under glove box.

PS: It was a struggle for the dealer to order N11 on a Corvette that was to be titled in Massachusetts back in the day.
Also was not allowed to have 3:70.1 by my father.
Out of the six Corvette's owned the 1967 was the favorite.














The Corvette had these factory options:

So, to be clear, you are not looking to buy the car, you want to give the current owner paperwork?

Tom McMahon

I'll surrender all the papers on the car, including the original sales agreement, and extra set of keys for the genuine car. from Curhan Chevrolet Randolph Massachusetts.
In the pictures of Corvette want to see the trim/VIN tags that are riveted to the tie bar/instrument support bar just under the glove box.
Don't care if the car is now black or Sunfire Yellow and has an L89, L88, or base 300hp 327cid.
This may sound eccentric, but would like to see Corvette 560 again.

Right now I have four high performance GM cars and could not effort to buy Corvette 560 if car still exists.

PS: I'm retired from Chevrolet team Corvette from GM Engineering Technical Center in Warren Michigan and seen many Corvette,S assembled at Bowling Green.
Bowing Green builds the most exciting cars in the world and will get more exciting in 2019 at the Detroit Auto Show.
With my contract time at GM spent 39.8 years.
Have seen the Corvette go to world class quality over the many years.
I have owned six Corvettes and currently own quick Z51 manual trans.

The so-called "tank sticker" started in 1967 was copy of build sheet/manifest and did not have any adhesive on the paper.
After the gas tank was checked for leaks pressurized and submerged in tank of water, the manifest was placed on top of the tank at right lower side directly. The paper got saturated with water and stuck.
This same process was performed in many GM plants.
Also at times the UAW person on the production line in St Louis would stuff another copy of the manifest under the dash.
Corvette 560 had copy under the dash.

I am not expert but don't think they would let you order close ratio with a 3.36 rear. Sounds like a neat car. That off road exhaust was the ticket. Good luck w/ search.

We actually have a place for this on the forum: On the main (General Discussion) page at the top, in the "Sticky" section, there is the ORPHAN VIN stamped parts and documents thread, where we try to reunite such items with the original cars.

Please copy and make your post there as well.

Hi,
You are not an expert and you are talking to the right person.
3:36.1 was the base axle ratio with L36/L68 and positraction was optional but required with these two 427 engines.
The L71 engine had a standard axle ratio of 3:55.1.
If I was the axle engineer back in the day the 3:36.1 would not be standard with L36/L68 engine.
The standard axle ratio for L36/L68 should have been 3:55.1 like the L71 specifications.
I was unhappy with the 3:36.1 axle. Although second gear was mighty strong.
Back in the day raced a Massachusetts State Police Cruiser. The Cruiser was 428 Ford. I beat the cruiser but was unhappy about how much.
Really needed 3:70.1 axle in my Corvette, which was the top axle ratio for L36/L68. 4:11.1 was not available for L36/L68.

PS: My 1967 Corvette came into the dealer (Curhan Chevrolet Randolph Massachusetts) two weeks before announcment date of September 29, 1966. Corvette was hidden from the public in a rear dealer garage. Back in the day these cars were covered from prying eyes.
Corvette VIN 194677S100560 was delivered with an engine piston slap.
I should have refused Corvette and ordered another.
The engine was replaced under new car warranty early.
So Corvette 560 was sold with replacement engine after years of ownership.


PS: The N11 option was supplied by "Arvin" to Chevrolet. It's now called Arvin Walker. Walker was the supplier for N14 (Dual side exhaust) AO Smith was not allowed to build side exhaust cars. all side exhaust car bodies were built at St Louis.
The N11 muffler had three baffles in lieu of five for the standard system.
The factory optional N11 muffler was stenciled on the underside of each muffler "OFF ROAD ASSY in yellow paint"
I miss the 1967 VIN194677S100560

Tom McMahon

OK.
Will look into this information.
Thanks
TomCorvette (That's my cruise night name)
Recently passed friend GM discount and he ordered 2017 Corvette Grand Sport Admiral Blue Coupe Model 1YW07 VIN 6850.
He is happy camper.
The Corvette was followed through the system right over to Jack Cooper transportation.
Corvette was intercepted by me at the dealer. The transportation cover was removed and car was inspection. The Corvette was in perfect condition.
Only one car known of came in damaged.

Tom McMahon

Hopefully surrendering papers, keys, and protect o plate will be incentive for someone to send me pictures of the real Corvette VIN 194677S100560.
I can spot the fake plates and the attachment of plates some people use.
In the past people have tried to sell clones.

PS: Another problem I had early was paint checking on the left top of fender near windshield reveal moulding. Believe this was caused by body twisting from large amounts of engine torque.

I had a 1967 Conv. 427/390 horsepower with a 3.55 axle back in the day. Good combo. Also had Transistor Ignition option, unusual. vin #21667 Yellow/Black, hope it is alive and well.

Tom McMahon

Believe that Corvette was built end of March or early April 1967 and was St Louis built body.
AO Smith did build some very early 1967 Corvette big blocks. However AO Smith couldn't perfect the silk screening operation of the hood stripe and Chevrolet removed the big block cars from AO Smith late August early September 1966. The only documented 1967 Corvette big block body built at AO Smith is VIN 365.
When I first saw my Corvette at the dealership noticed that Rally Red paint could be seen through the black hood stripe and my car VIN 560 was St Louis built body.
Dealer refinished the black stripe less the black striping under new car warranty and did do great job.
Your Corvette VIN 21667 had the 3:55.1 axle at extra cost. You also had to buy positraction with that power train and positraction was optional.
Certain power trains required posi axle.
My Corvette 560 also had optional RPOK66 (Transistor Ignition Equipment) On the L71 cars people were forced to buy K66.
Early in September 1966 my K66 failed. Water infiltrated the electronics and system shorted out.
Although the car was under warranty my father knew what the problem was and brought home new controller and new box cover gasket.
This was the fix. The problem was really the gasket assembly.

Tom McMahon

Hi,
Did you ever experience water leaks on your Corvette VIN 21677 from water entering plenum and over coming the air vents in heavy rain storms?
My Corvette VIN 560 had this problem.
During heavy rain storm October 1966 my foot wells were full of water and Corvette was closed up tight.
I had to pull the floor panel front plugs to drain water to drive car to work.
The dealer did make a fix and replaced the front black carpeting.
I never found what the dealer did for fix.
Do you have any ideas or comments on the above water leak explanation.
Did your Corvette leak water?

Mid year BB cars had a poor survival rate due to the way they were raced and abused. There are now more BB '67s for sale than ever manufactured. Can you spell 'FAKE'? lol

Tom McMahon

Hi,
I agree about the fake 1967 Corvette 427's for sale.
My Corvette VIN 560 is for real.
I have the papers to prove #560 is L36 1967 Corvette.
My original engine had a piston slap and was replaced under new car warranty after a few months of ownership.
I'm the original owner of VIN 194677S100560 (L36 427 390HP) built September 09, 1966

lynndm

My comment is just a general observation based on many years of NCRS membership. I didn't mean to imply that your car wasn't genuine. Apologies if you took it that way.

My first Vette was a '65 300hp Marina Blue coupe in college. Due to many disagreements with area law enforcement about the prudence of my driving habits, my monthly insurance payment was higher than my car payment so I bailed after about 6 months. I next bought a beautiful '62 hardtop only roadster that I successfully raced Modified Production for a few years.

Every time I sell my 'last Corvette', I get that yearning again!

My first Corvette was previously owned.
1960 Corvette Hondurus Maroon with standard black interior, standard black wall tires, and standard black convertible top.
The engine was mechanical lifter 283CID 270BHP, 4-speed close ratio T-10 transmission, and 3:70.1 positraction axle.
The Corvette was solid Hondurus Maroon and not two tone.
Car sounded like the straight through muffler system that I believe was standard on high horse power engines back in the day.
Although some said the Corvette was ugly, I loved this machine.
Today I own Z51 Corvette. Purchased Corvette before retiring from GM Tech Center.

Tom McMahon

PS: Back in the day drove 1965 Corvette. This 65 had the 327CID 365BHP mechanical engine and 4:11.1 posi axle. What a rocket she was.
On insurance. I could not get insurance at twenty years old for brand new 1967 427 Corvette. My father was good enough to put the Corvette in his name so I could drive the Corvette.
My father insured the Corvette with Motors Insurance Company back in the day which was division of General Motors.
The MIC agent warn me one time. He said do not smash it up or you are done with us.

That VIN does not show up in the NMVTIS. Which proves nothing, but it's not encouraging.

Tom McMahon

Hi,
Thank you for the thought and help finding 1967 Corvette Convertible VIN 194677S100560.
What is NMVTIS?
I hope the Corvette is not now scrap or part of other Corvettes
Always wanted to find this Corvette in fair or restored condition.
This Corvette number 560 is real L36 427 390HP.
Very early 1966 Corvette's L36 was rated at 400 horse power.
Still hoping Corvette number 560 will show up some day before I pass.
This Corvette also real N11 Corvette. The option was $36.90 less 25%.
My father got ths Corvette at GM class A pricing back on September 29, 1966 from Curhan Chevrolet Randolph Massachusetts.
The Corvette was actually in his name because I could not get insurance on new 427 Corvette at twenty years old.
My father was good enough to place Corvette in his name so I could drive car.
I regret not allowing my father to drive Corvette to work at GM Assembly back in the day.
I was afraid of other employee jealousy and damage to the long awaited Corvette.

PS: Back in the day it was best that GM employees leave their new Corvette's at home due to jealousy. This statement may be hard for some people to understand.

Good luck with the search for #560. My car was #00434 built on the same say as yours and is also a 427 390 hp car with 3:36 gears

Tom McMahon

Cool.
This makes sense about both VIN'S being built out of St Louis Assembly with the bodies built at St Louis and not AO Smith (A Dow Company)
What do you think about the standard 3:36.1 posi gears. My father would not allow lower gears on my order back in the day.
As you know other axle choices were available. I should have have called dealer next day at home and put in either the 355 or 370 axle.
Was your car 37 or 67 style? And did you have m21 or m20 transmission. What was exterior color and was this A82 head restraint Corvette with shoulder belts?
To be honest my Corvette 194677S100560 wasn't the best quality Corvette ever owned. Had many problems that shouldn't happen.
I would like to have the Corvette #560 back. All the items were fixed.
The big item was piston slap with brand new Corvette.
I actually blew engine to get new short block under new car warranty.
Corvette #560 was my third and first new Corvette. I liked the sound of N11 off road service accessory mufflers that I had struggle getting from dealer.
Dealer told me I couldn' t get inspection sticker in the State of Massachusetts with off road exhaust, but option did hapened on Corvette #560 @ $36.90 less 25%.
My father got Corvette #560 @GM class A discount back in the day at 25% of MSRP of rounding figure of $5,300.00.
Actually my father was hourly UAW member back in the day and wasn't eligible for class "A" discount.
All was needed was a quart of Whiskey and a GM salary person'S authorization number for hourly to get class A discount back in the day.
Today getting GM discount for all employes is totally different.
My last GMS on my Corvette was only 16%.
Today its only 13% off Stingray/Grand Sport, and 11% off Z06
