73 kframe on 72 abody

The K bolts, are a tapered shank design. These are special in the fact that the tapered shanks on the bolts exactly fit the K frame bolt holes. The K frames are built on a jig at the factory to an exact dimension. This is so on the production line when the k frames are bolted up they fit exactly the same. Any adjustments end up having to be made in the suspension for alignment. For this reason, like a previous poster said , if you enlarge the bolt hole you are not correcting the problem. Only putting a bandaid on a bigger problem.

This being said, if your new k frame has a hole thats 1/16" off in relation to your framerail after you bent the old K frame by hitting something, then its your framerail thats out of alignment and not your new K frame.

Easy test is stick your old K back under and see if all its holes line up, if it does and its bent, then your framerail is likely bent as well.
