Default trim plate decode?

Anyone have any knowledge in this area, i have found sites telling what month the car was built by the serial number and telling trim and paint, but not been able to decode the trim plate code beside the chevrolet. They are a letter than 2 numbers? I have D09


Anyone??

Thanks
Andy

The letter is the month, the numbers are the day, of the body build date. There are also numbers that designate your exterior paint color and interior color. A = the first month of production, for the 1975 model year A = August 74, so D09 = November 9, 1974.

D is the fourth month of production, 09 is the ninth day.

The first month of production changes from year to year. What year is your car?

It appears you have a VIN from one 68 and a trim tag from another. I seen this once and the owner wanted a yellow car and his car was whitewith black interior. He painted the car yellow and got a yellow with black interior trim tag from a dealer who parts out vettes not knowing about the date on the trim tag.

68 Vette 04299 was built Nov. 13th 67 and would be C-13

68 vette trim tag D09 was a Saturday and my book shows no production that day. The last VIN on Dec. 8th 1967 was 06354.

They are from two different cars or the factory goofed.

I would check for a sectioned body two bodies split in the middle to make one from two wrecks.

Thank LYLE
I just bought the car, and it appears the vin on the windsheild frame is correct and original, and doesnt look like the trim plate has been removed before either. So far it looks like the trim colors match the original paint too?
This is a project car, and was missing the front end, but apart from the front end missing, the tags all look like they haven't been played with

What book did you use? Its nice to know what day the car was dated even without the correct trim plate? Does the book brake down sequence numbers per day?

Thanks again for the answers

Andy

I used the NCRS birthday book. It was made from the known last VIN each month and is an estimate using all known days that were worked each month. It usally very close to correct. If your car has any other original dated parts I could maybe solve the mystery. Dates on back of the speedo and tack. Transmission , engine, rear end, intake , carb, ect. Any of these after the VIN date would make the Vin wrong. If all dates are before the VIN the trim tag is wrong.

The "D" on your trim tag translates to November for 1968 production. (Started with "A" for August that year, and so on.) "09" would be November 9 of 1967, a Thursday. Your car then rolled off the line on the following Monday, the 13th. Perfect!

guys! It is well known that the online birthday calculator you are referring to as "gospel" does not give correct answers for 1968 model year! (Maybe they fixed it, maybe not)

I have 1968 #4473 and it is a D13 build = November 13, 1967.

AndyMcleod, if you have 1968 number 4299, and it is D09 that would be November 9, 1967 build date which is about right.

As a better source of information, take a look at the 1968 registry. There are a few entries that don't fit, but for the most part you can check the vin and the build date and see where yours fits in.

from the 68 registry:

4157 = D08
4205 = D08
4235 = D09

Maybe what adds to the confusion here is that the date on the trim tag is the date of BODY production, not final assembly! Final assembly usually occurred a day or two later.

The black book shows no August production also so gm must have made no A's and started with B. I should have known better than try to help a 68 owner. All my information must be wrong but glad your car is OK.
Sorry

I looked in the Birthday Book, and it shows that '68s through serial # 0045 rolled off the line (final assembly) on September 1. If the bodies had to be made at least 1 day before, that would mean they were made in August. That's why you'd probably find the first 45 or so 1968 Corvettes had an "A" on the trim tag.

Wow, thanks guys.
I was worried that D09 meant dec and not nov, thought A would have been sept start. So as long as D09 was Nov '67 im a happy camper (i was born in nov 67, and was a big reason why i bought her). This decode stuff is very new to me still, until a few years ago, i was only mopar, now only corvette 8). LYLE, its ok, i'm happy you jumped in.
So far engine block matches vin, and rest looks like its orginal too.

BTW, where is the 68 Registry??

This all makes sense now. They put trim tags on a few 68's in Augest 67 with an A but none came off the line till September. I did check my NCRS 68-82 Corvette specifications Guide and it shows A for August 67. This may be the only year this happened as from 73-82 I am pretty sure it didn't happen again. At least I learned a new fact today and may see it again and know the correct answer.

My car is 4205 with a D08 trim tag. Must have been the last one they made that day!
