Besides the 8.8 setup everyone is using, are there some factory options for differentials? Will RX7 or RX8 diffs work? Do they bolt in? I'm just curious what kind of options I might have. I'm probably about to trade my Msutang for a Miata, and a good friend of mine just gave me a pile of LS1 parts, so I obviously have only one choice....SWAP TIME!!!!

You might be thinking of an FD diff which came with a torque arm, turbo 2 diffs in the FCs didnt have torque arms

You could use the bolts with a torque arm though prob, as it works similarly

TII aluminum housing + 1988 929 carrier with 3.73 gears + TII diff = direct bolt in factory rear end with limited slip and 3.73 gears.

Looks like the issue would be that the diff is shorter thus the rear flange will hit the rear subframe.
