Are you replacing factory G80 with the Auburn or is there no LSD now?

I believe the gears in the truck are not the same as the ones in the f bodies.

They're not the same at all. Cars have a 7.5" ring gear and the trucks is an 8.6" or something. But there is a huge difference. Don't attempt it, and be down both cars! That would suck!
