There are partial VIN's stamped on the frame, engine block and transmission. An example would be 28P123456. 2=Pontiac Division, 8= 1968 Model Year, P= Pontiac Michigan assembly plant and the last six digits will match the last six of your VIN, assuming your car is numbers matching.

There is NO VIN stamped on the data/cowl tag, I have an example picture; 05C is the build date, 68-24237 = the year and the model, 2=Pontiac, 42=GTO and 37 =Coupe. The 20840 = the 20,840 GTO coupe built at the Pontiac plant. 223 = Black bucket seat interior and Q-Q = Verdoro Green upper and lower paint, but again there is NO VIN on these tags.

Also starting in 69 I have seen the partial VIN stamped on the firewall under the heater box/blower motor, but I have never seen it stamped there on a 68.

The information regarding the the 6-digit serialized production number of the car produced is mistaken. That represents the 20,840th V8 car produced across all models and does not correlate to overall GTO production! :-) GTOs produced at that plant will be far less than that number at that point-in-time.

I would have to respectfully disagree with that statement. I have collected data on over 500 68 GTO's and have it all in a spreadsheet. The highest GTO coupe body number I have from the Pontiac plant is body # 26154, 07C build date, and VIN sequential #370088. So that car was the 270087th V8 Pontiac built at the Pontiac plant since the sequential for all V8 plants started at 100001. Six cylinder VIN's started at 600001, I have not collected a lot of data on those cars. But by far the Pontiac plant built the largest amount of 68 Pontiacs. The home plant probably built close to 40% of all 68 Pontiacs.. Also I have data on a 68 GTO conv. that is a 07B car and it's body # is 3859, obviously the Pontiac plant didn't build 22,000+ cars in one week! The convertible's VIN is 361454, so that is a difference of 8,634 V8 cars built at the Pontiac plant. Another example is the difference between GTO and LeMans production, I have a 04E GTO coupe with body # 19545 vin 292899, a 04E LeMans coupe with body # 31575 vin 298687, then a 05B GTO coupe back down to body # 19801 vin 301991. All the plants exibit the same sequencing of body numbers to vins, except for one, the Framingham MA plant. Your statement holds true to that plant only, but that plant was the oddball. I can also deduce that the Baltimore and the Pontiac plant built about 4000 convertibles each for a total of 8000, the other 4 plants built the remainder of 1,980 conv. GTO,s. The Pontiac plant built about 26,154 GTO coupes, or about 33% of all coupe GTO's. I have data on the Framingham plant of a 07C GTO coupe with body # 104787 and VIN # 142443, also a 68 07D Chevelle with body #107044, so I think they sequenced body number regardless of make, but like I said that plant is the odd-ball and the only one that I have seen that did it that way

I am just revisiting this thread after a long hiatus. Having re-read my statement and then your response (several times), I believe we are actually saying the same thing! My point was addressing the VIN (6-digit sequence) not BODY number. Therein lies the confusion. As you point out so well, the VIN is sequential for V8 cars for VINs beginning 1-5, 6 cyl for VINs beginning 6.

The body number is, without question, sequential for a GTO vs LeMans. The convertible body sequence is separate from the Hardtop body sequence also. I do not have as much information collected on 68 GTO VIN / body number as you - perhaps 100 all totaled. You have great knowledge. Thanks for sharing.

hello,

i am trying to get info on our new to us 1968 GTO

vin 242678B133242
engine 709541
YS

We were told that is all matching numbers when we bought her.

Thoughts?

Thank You

Welcome to PY, Tim!

The engine may have a partial VIN on it down lower by where the timing cover mates to the block.

Should look like 28B133242 in your case.
Date code on the back of engine by the distributor would also help.
