As an aside, I do see references in other postings of 'shimming' of boxes. Does this mean what I think that it does,,,shimming the box to accommodate out of kilter boxes, or is for out of kilter 'K' members?
It is a production error with the boxes, not the K frames. Earlier in this thread you'll note we throw a stock box back in and everything lines up. We ended up shimming ours with a couple Williams washers.
Also of note, I believe Firm Feel can make an "unkeyed" pitman, or you can meticulously grind the larger key ways out of a standard pitman to make it infinitely adjustable.
