ok guys im looking at getting a new rear for my Z28, the only place in UK with one at the moment has a 98 RS V6 diff. It has rear disc brakes.

There is no drivers dorr so i cannot get the codes. I have the question is the diff a POSI/LSD torsen or Auburn, and is the ration for an auto a 3.42??

thanks

 

build codes are usually inside the glovebox door,not sure about '98 but previous codes were...GU2=2.73 ratio,GU5=3.23,GU6=3.42,G80=rear positraction,limited slip.
