I have a 92 RS and I am planning to swap the stock 305TBI to a crate 350 then Intsall an aftermarket fuel injection system, while in the midst of all this I plan to install a new Differential since the stock one is supposedly limited slip but always spins one tire and always the same one, I still want a limited slip and still want to keep the 2.73 gears since larger gears and true posi put a real damper on gas mileage. I just want a better limited slip that actually locks posi when doing drags and such but still has the charachteristics of a limited slip for gas mileage. I need to know the details of my rear end and differential, and if anyone has any suggestions on differentials theyve swaped or bought and used I would be open to any.

Sincerly,
