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.
