If it's just the first couple of threads on the bolts, either get new bolts or take the right size nut and thread it on the bolts to clean them up enough to start; you can also grind the tip of the bolts to a taper so they'll start cleanly - there's plenty of threads left.

If the bolts threads are really buggered, you can take a swiss file and cut threads by hand if you're careful... of course, it's best if you have an actual tap & die set!

 

alright guys, i played around with it last night and got them to fit! Seems the first few threads were bad but not totally bad and I somehow got them to work. All is good except now when braking hard the truck pulls right...????

 

The right front isn't braking as hard as the left front brake - or - the left is braking harder than the right - why?

Caster, camber, and toe - the left brake will pull right, and the right brake will pull left.

Unless your alignment is all messed up, of course.
