toycoma Don't listen to that fool JDMvigor, he drifts with his sandles :icon_mrgr
check it, I did put the 3.71 LSD in my cressida few weekends ago. Looks like the Guts can be transferred into the x83 diff but I opted out of that piece b/c you would need to get new seals and stuff when you start taking the thing apart. It would cost more $ in the end. however, I did my 3.71 setup a little different from Brian and Scott. insted of cutting a hole in the Rear cross memeber, I welded a spacer to the upper part of the cross member with it in the car, and then welded the bolt to the spacer, used the 1/2 inch rubber bushing that comes on the x83 cross member and used a nut at the bottom. seems to be holding just fine..
