Once AMC was bought by Chrysler it opened up all those engines and rearends to be used in AMC cars. Wasn't a Dana 60 used as OEM in the Super Stock AMX .

IIRC SS AMXs used the AMC 20 axle with Henry's axles.

Somehow I have trouble understanding how NHRA considers a 56 Chevrolet to be "less" of a GM product than a 57 Pontiac, compared to an 60s or 70s AMC car is to a Chrysler product, after AMC was bought out by Chrysler in the 80s!

GM is not the manufacturer, Chevrolet is.

I have looked at a lot of center sections of the rear ends in lots of brands and I see GM cast into the casting not Chevrolet or the other GM brands.

If the previous statement is true, there are a lot of BOP and Cads out there with 12 bolts. Travis may be able to chime in on this. Or are all those cars not legal?

I understand the perspective, but consider that the corporate structure of GM related to the different manufacturer brands is different from the other corporations and their brands. Chevrolet, Pontiac, Oldsmobile, etc. were all considered to be totally separate entities since they all started independently and then brought under the umbrella of GM. Ford and Chrysler both created all their brands from top-down decisions. The brands of GM chose to be part of the consolidated group to work together, but not to be controlled by the GM corporate office. As a result, most of the design and manufacturing up until the late 70s was done independently from each other. The rule says "of the same manufacturer' not "the same corporation".

I know for a fact that the 1970 GTO with the 455 engine option came with a 12 bolt. It is also a fact that some Buick Skylarks built in 1970 had them.
