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.

This is an assembly line installed Dana/Spicer 44 rear in an '82 Z28:



But back to Rod's question...why wouldn't you want to run a 12 bolt? -Al
