Motor mount "looks" a little old. But seems like you need to move away more than just one replacement mount.
I believe they make a truck mount that is thicker. But looks like you're going to need a dimple.
I don't think its cost effective to buy a new K-member purely to take a chance that it solves this ? 1/2" clearance issue. The money, time, effort just to bank on 1/2 quality control (dimensional stack up) is too risky.
Not that is bad, but looks like there is an repro motor mount bracket used. Just another variable.
