Hi all-

Ok, so I got motivated and found a friend with a 4.11 rear torsion diff for
$500. I know to repack the CV joint when I do the swap, but what I realize
I really need to do is the rear subframe and control arm bushings.

Does there exist a parts list for the bushing job, or a microfiche?

Are there aftermarket bushings available? Poly or Derlin?

Thanks and I'll share the process as it unfolds.

monster"
