Jeff, This is a very good post. The Tech Service Bulletin is some strong evidence for the 68-72 CHEVROLET Axles. This brings me to the newest question. Since the 1970 Trans Am and the 1971-1972 GTOs used a Chevrolet 12-Bolt axle wouldn't it be safe to say that these cars would be a Black Axle and backing plates. I am restoring a 70 TA right now and feel this should be the case. I may have to create a new thread regarding those models to get the attention of the 70F and 70-72 A Pontiac owners. I would refer people back to this thread to review all of these great posts. Any thoughts on the Pontiac's with the Chevrolet 12-bolt installed before I start a new thread? Also the 71 up Pontiac Firebirds used the "Corporate" axle same as Camaro so.....would that be all black as well..
Thanks for all the participation with some great info.
