10 bolt question
And the gears are the same too. 2.73 or 3.23 for auto and 3.42 for manual.
But it wouldn't be an upgrade but would get you back on the road quickly.
You can also look at a Ford 8.8" rearend out of a Mustang. With some fab skills, you can make it work and it's far more robust than the 10-bolt. Or a 12-bolt out of an older GM car or truck would also work if fabbed up.
Another option would be to buy the housing yourself. I'd look at a 9" - and there are lots of shops that sell 9" housings, axle tubes, and axles for the F-Body. Then you can buy the center section, gear set, and a rebuild kit and put it together yourself from probably $2000-2200 or so.
The cheapest fully assembled and ready to run rearend is probably the Strange S60 with a spool or a Moser 12-bolt with a Spool. I'd stay away from a Moser 12-bolt because of how the torque arm attachment works. The 9" housing from Moser is great though. The Strange 12-bolt is more expensive, but has a standard TA attachment point and works well. The 12-Bolt spool can handle quite a bit but is weaker than a 9" or S60.
