I have a gearbox was going to do a quaife Lsd swap they have opened the box and found it has a factory fitted lsd to put a quaife in I will need a turbo gearbox non factory lsd and put a quaife in that as a factory lsd box is different to a factory non lsd so now I have a factory lsd box on the car which came with the car so I didn't know it had it until now and a brand new quaife Lsd with bearings that won't fit in my box am wondering should I just put factory lsd box back on or is it worth sourcing a non lsd box and fitting the quaife Lsd in is the quaife alot better than factory lsd is it w
