Being a 9737 car....wouldn’t the axle code be QD ....and not BU ???

The Rally Green non converted car was BU also.

But wasn’t that car a Nova ??

Nope. 68 Camaro.

Maybe the non-conversion transplant encompasses the BU ...is it real born with to the car ?
So I could assume the QD 4.10 code application only applies to converted cars with Copo specifics ...except for 1 documented transplant converted 68 that does not have the 9737 as is also Corvette Bronze

Read this article. It discusses rearends towards the bottom. This rearend is original to the Car. I don’t believe it had anything to do with whether the car was converted or not.

Not to be judgemental....but since you are offering up this car for sale ...people would like to see photos of the rear axle code and especially the date .
