Does anyone in the Toronto / Southern Ontario region have a functional differential centre section they'd be willing to sell? My diff needs a rebuild and I'd like to be able to keep the car mobile while I'm working on the diff rebuild.

Ideally it would be a limited slip unit. Gear ratio isn't too important. My 85 manual trans car has the 3.72, which is obviously incorrect. So if I could get a 4.10 or 4.30 then great, but a 3.72 wouldn't bother me either.
