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 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.

Don, I guess you are saying that at least one Cad had a 12 bolt. ;-) A lot ? Doubtful..some of the other 2-3 had 8.5's.

B-O-P are all covered for 12 bolts in the 70-72 era.

Here's something to think about on Chevy rear ends:

-Some '82 Camaro's came with the Spicer (Dana) 44 rear axle.
-So a Spicer/Dana rear axle would be a 'Chevrolet' rear end.
-So if a Spicer/Dana is a 'Chevrolet' rear end (and we just proved it is )
-You should be able to legally use, oh...let's say...a Spicer/Dana 60 in any Chevrolet stocker.

I rest my case. -Al

Alan, that might be a tough sell but yes, GM offered a Dana 44 rear as a "service package" replacement for an early 80s Camaro/Firebird with the 305 HO engine. Contrary to the NHRA Guide, the 305 HO was a stick only combo and they were constantly breaking the 7.5s. I have never nor do I know of anyone who has ever bought one over-the-counter but they were the replacement for warranty claims. I've had a couple of them over the years.

I believe that the Dana 44 was factory installed in the early 1LE cars.

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".
