Rear differential info on fender tag ?

[44o gts dart]

Question??? Is the rear differential ratio 3:55 (567) , or 3:92 (568) found anywhere on fender tag of 1969 gts M code ? Or is it only seen on broadcast sheet and window sticker?? The carrier is gone ‍

I'm guessing it may depend on the assembly plant. The code for the rear-end for my A12 runner is on my lynch road tag.

But all the literature states that 3.55 is standard and 3.91 was an option…

Did,a little more research, saw a fender tag of a real 440 Dart. Apparently the Hamtramck tag does not show the drivetrain build codes , like my lynch road b-body tag does. It doesn't even show any "A" codes. Just the "M" and Y39.
The tag I saw is for a car that the owner had professionally restored, and claims it has the optional 3.91 gears.

I agree, neither my M-code ‘cuda nor my 340S Barracuda, both Hamtramck have the rear end code listed on the fender tag.

That’s exactly what I had found,,,the lynch fender tags , were throwing me off. Thank you all for your research and time
