How many miles on the car?
The bearings should be fine, but I think Ford Racing makes a install kit, as well as a rebuild kit for the Traction-Loc, depending on the need and miles.
75-140 Gear Oil
IMO Brace is not a option. You NEED it, these cars should have come from the factory with them. It's hard to explain, but every time you get on the gas, the way the diff is mounted, the cover tries to pull off of the diff housing.
You could also burn up money with gauges and stuff, then just get a nice SOS pod to put them in.
Tim-Count me in.
We got a few Sat's left @ The Valley!
