1968 'unique items only' list?


I just bought a great 68 convertible that I am going to do a full frame off resto; (I will post pictures soon, and over the next year or so);
I read somewhere on here that someone compiled a list of items were unique to a 1968 only - does anyone have that?
Thanks in advance.

Purchase the 1968 assembly instruction manual (AIM) and use the original GM part numbers you will find there for comparison with similar parts on later cars. THE NCRS Judging Manual is also helpful. The 1968-72 Corvette Fact Book by M. F. Dobbins is also an excellent source. Great underhood and interior pictures of original cars.


some more one/ part years include
The 68 steering wheel is a 16" wheel, and the colum itself is a carry over from 67
The 68 had a nose support bracket that was part year only, none for early models
The vent ***** one year only, early 68's had the overide controls more to the lright near the console (moved to center later)
Of course the push button door openers, and wider door panels. door pulls added for later 68's, the hidden ones would crack
the use of a wiper overide warning indicator on the guage cluster
the console plate was one year only with no engine ID plate
7" rims for the 68
one year only large journal 327

under the dash, the original 68 switch has a toggle type switch (later models used a plunger type) that when you press the pedal the switch closes the circuit and the tail lights come on. when it goes bad what you see is people using the 69 and later switch as a replacement using a different mounting bracket.
68's rock, we'll have to link up sometime, my vette actually came from Niagara falls when i got it 3 years ago
some other things that come to mind,
true quad tail lights with reverse on the lower valence.
wiper motor and associated wiring is one year only
if you have the high horse 327 it came with chrome stamped valve covers
the 68 bumper is one year though a 69 will interchange with it
the headlight doors had a part year configuration late and early
the gas tank is a 20 gal tank
the steering damper on the drag link was a part year option, later canceled
the early 68's Gauge cluster has a smooth finish vs the later pebble finish
the parking brake console had pockets for the seat belts
68 was the last year for an external voltage regulator, with associated wiring harness differences
radio ***** were a one year style
Tobacco was a one year interior color option as well as the comfort weave seats
the panels that attach to the side of the forward console were a part year release, some just had a clip while later ones had a screw fastener
the shift early shift boot was part year later ones went into later models
the 68 tach cable was screw on vs the later clip style
body mounts were solid aluminum, later years were rubber (I have heard some 69's had the solid mounts but never seen it my self )
rocker covers were a two piece design that carried over into 69
dash wiring harness
headlight swithch bezel
vacuum hose set up
Front grill and painting
I'm sure some others will come to mind
small block intake with oil fill tube
early ragtop latches
cheers

the whole column was a carry over from 67, you can use the switch from the same year biscaine as well
how about 4 tail lights and the valance for the backup lights. Front spindles are as 67`s and earlier. 9`s and after are different bearings. Shifter **** is chrome plated and not plastic. No tilt or telescope either. And my favorite is it`s not a stingray and has plain gills, no chrome on them. As well as I know there is only one grill throughout the 68 model run carring chrome only on the leading edges on the center 4 ribs across the whole grill, including the center. It also has a small front spoiler.
Early interior door handles were smooth vrs. ribbed on the back (inner) side.
Windshield washer nozzles mounted on grill behind wiper door vrs. on wiper arms.
Front grill brackets unique.
Early sill plates WERE wider on the innermost side.
Front spindles are smaller diameter (same as mid years)
Lower valances did not have cutouts for air flow----Dealers were instructed to retro cut these.
Real halo panels (on coupes) were configured differently.
Pop out rear window latches were different shape.
T top stainless trim was different configuration, as was the weather stripping.
No stainless "tips" on the hard top.
No bumper stops on read convertible deck lid.
Bolt holes on frame horns and their extensions were of a different configuration.
Angle on end of front bumper reinforcement extensions was different.
No gromments were used under the interior dash screws.
Shoulder belts did not retract, had a "hanger" and did not have the guides on top of the seats.
I know there's more......

I know there was a real push to get the 68 finally into production... BUT... why SO MANY 'one year only' parts ?
It seems like some changes were for 'function', some for 'style', some for ???.
What happened ?

The 59 and 60 comes to mind where its almost impossible to tell the difference at first glance. 53 and 54`s were another closely identified year where it was hard to identify the year. So, changes were not unusual. 62`s are another look a like with the 61`s. But nearly all the major body pieces are not interchangeable. Take 63`s, another maverick Vette with a list of changes as long as your arm with differences as to a 64. First and last years of a basic body style seem to be the worst offenders....
Some of the previous posts are not quite correct in their listings, a lot of the '68 only parts were used either in 1967 or 1969, so they are not one year/ unique as stated.
Dont forget the first part, THE FRAME!
The 68 frame is one year only, and changes near the end of the year.
