otherwise.....
I have to find out what aftermarket LSD works with a Q45 diff...
according to this..
Install Guide: Q45 Differential swap into 240SX subframe - S-Chassis.com
if it shares the output shafts of a 300zx TT so maybe I could just buy a Kaaz for a TT and that would work
probably just need to get my lazy ass out there and take it apart and count the output shaft splines and see
