The rear was a 8.5" 10 bolt. It was shared by the Nova as well as all the X-body cars. The Nova offered the 12 bolt also in earlier years! I have a 10 bolt that might be going up for sale with 4.10 gears and posi, I am looking to upgrade to a 9" rear!

This should help, Bob. From the GTO Little Red Book. It appears that only 2.73 and 3.08 were available.
