I have a question, from what I understand on 69 Z-28's the VIN along with the engine code
was stamp on the front right side of the engine on early Z's and on late Z's the VIN was stamp by the oil filter. Is this correct and if it is what date makes Z's early and late model? From what I understand 12B is to be the divided from early and late Z's. I have a Z with the VIN stamp on the right front block which would make my Z a early Z.
VIN # 12437N552441

TRIM TAG #
ST 69 12437 NOR103816
TR 713 72 72 PNT
11D X33

BLOCK
vin on block 19N552441
engine code on block V1105DZ
casting # 3932386

Going by the information above this would make my Z assembly block date Nov 5th day and
Vehicle assembly date Nov 4th week which is correct, engine assembly before vehicle assembly.
The casting number from what I read is this block was used approximately August of 68 to January of 69.

Also I have read that the X33 code on the trim tag was only on late 69 Z's.

Can anyone help?
My question is does all this seem correct

Welcome to the board dgonzale! Another Camaro lover from Dallas! Are you a member of the North Texas Camaro club? Have any pictures of your car?

Anyway, I'm sorry I don't have the answer to your question, but I recommend that you post it in the Tag Team forum. You're more likely to get a better response there than in with the general tech info here. Good luck!

I was under the impression that the X_codes didnt start until 12B yet yours is an 11D
which still could be if it was 4th week of november of 1969 My car is a 10D but the sequencial number is N702853 your vin number reflects a pretty early build N552441 which would make it before the X codes were used
Now I am confused as well anybody have any more info on this???

The oddball in the equation seems to be the x33 code on your trim tag. Everything else according to my info checks out.The next thing to look at may be the actual size of the tag, on early cars it measures 1.75"x3 15/16". Later cars were 2 1/8x 3 1/2". Also does your car have the x33 trim accents such as simulated rear fender louvers, bright headlamp and tail lamp accents and front and rear wheel opening mouldings? The I.D. #103816 doesnt jive either as this would put it into early Sept. production. (check to make sure its right) Hope this helps

A couple of things don't jive. That body # is too low and X33 shouldn't be on the tag. But I'll give it the benefit of the doubt so we can prove it one way or the other.
Can you send me a picture of the VIN tag, making sure the rivets are visible?
What's the #'s from the trans and rearend? Trans is stamped on the side and the axle code is located on the passenger side axle tube. Look under 'Decoding' on the CRG website for a great sketch of the location.
