Brand new: FRPP M-4001-S327

Basically, a 3.27 8.8" Traction-Loc right out from under a 99-04 MGT for $700. That's a pretty good deal:

Used: Junk yard. Make sure you find one from a 99-04 since they are 1.5" longer, end to end, than 95-98 assemblies.

Swapping an axle isn't that big a deal. Four bolts and some ancillary stuff (e.g. brake calipers, driveshaft etc) and the thing falls to the floor. Just be careful when working near the coils.
