for the rear, you can go to home depot or orchard supply to get longer bolts and some more washers. the bolts are M10 x 1.25 pitch. i believe stock is 40 mm in length, i got 45 or 50 because OSH didn't have longer ones when i went.

the SPC ball joint kit should work well and most likely nothing will need to be modified (fender or shaving of suspension components).

do you know what your camber is right now? it'll help you select the right ball joint kit and the number of extra washers.
