Re: front pinion shims

While I would never even think about putting lift blocks on the front, I do have a pair of 2 deg. shims to help with the pinion. I keep an eye on them and make sure the nuts and u bolts are tight. So far @ 10,000 miles and they have not had a problem. You are right about the shackles though, they don't help things out with respect to pinion angle.
