Re: Cab too low at the rear, any ideas?

do you have the right bolt size? the frame side bolts are supposed to be an exact fit in the frame holes. if you used smaller bolts with a clearance fit, it wouldnt surprise me if it first slipped to the bottom of the clearance fit (small change) and then beat the frame hole ovaled over 700 miles (big change).

same with the upper shackle bolts, should fit the hole exactly, and there is usually a shim on the bottom side, not 1/2 inch. the bolts install from the bottom to the top, with a threaded plate on top.

here is a picture of the set I just took off a 54. the shims are on top, the plates are there, and you can see the shoulder on some of the bolts.
