Jason, Search the archives for Jim Forbes past posts titled Rearend primer, and
Rearend primer II. This will answer your questions. Jim is our resident TF
rearend Guru. He's helped me out alot! Warning: some late model Camaros and
T/A's came with a 9 bolt (yes 9 bolt) rearend with disk brakes. They are made
in Australia by I believe Borg-Warner. Avoid these! They break, parts are hard
to find, and not many choices for gear sets. In my opinion, the best rearend to
use is the one you already have! 70's 12-bolts are the way to go. Take the
money you were going to spend on a new one and buy a Classic performance
Products rear disk brake kit and a ring and pinion if you want different gears.
That's what I did. Most folks seem to think rear disks are not necessary but I
like them. Don't forget to use a proper master cylinder and residual valves!
When changing brake systems do your homework! - Jeff
