FD Diff in a FC TII Rear End Questions

Christopher W. · 06-16-2008, 09:13 PM

I have a 1990 TII rear. So are you saying I still need to get S4 stub axles? Would that mean S4 haft shafts or S5? Or are they the same?

I bought a 4.3 R&P for a S5 TII rear. Should I order pinion bearing for S5 TII?

I am not doing the work. A guy who builds American racing engines and rear ends is. He isn't exactly familiar with Mazda rear but can accomplish what has to be done. I am just trying to get the correct parts to him.

I don't really know what backlash is but I do know it has to be set by someone with the right tools and knowledge. Macon Motorsports is handling all of that.
