The Brakes....
I decided to upgrade these too... so I got a Wilwood 14" setup front and rear. Really like them.
The fronts were no problem...
For the rear, I had some fitment issues as the caliper mounts hit the trailing arm pads on the diff. #narroweddiffproblems
So I setup a ghetto mill consisting of a new router bit, my workbench and some 2x4s and lots of cutting fluid and very carefully, very slowly milled out a relief so that they would clear.
