Before I embark upon cab repairs I am taking advice from members here and rebuilding the rear shackles.

I see there is a need to get a specific height between the rear of the can and the frame and already have shims for that.

However, upon dismantling the rear shackles I am noting 1 or 2 of the 4 bolts that go through the rubber bushings have worn so badly they are out of round. When I tightened them back up with new bushings they would barely rotate even when applying max pressure. The ones that look to be round rotate fairly easily. I am not doing anything more than getting the cab mounted for repairs at this stage so will drill them out and replace with grade 8 bolts.

I guess the question is...I looked at the prices of replacement mounts (!) and am wondering whether the grade 8 bolt route (or other suggestion) is a problem for on-road use or whether I need to simply stump up $220 for replacements?
