K member swap and upgrades. Bergman pins

I would just put a couple tight fitting washers welded fore and aft, but having a bit of movement in the pin, who knows exactly where to put it? I welded a washer to the last Kmember, on the torsion bar side trying to clean up some slop and ended up have a TB that did not want to go in. Upon disassembly, the pin was bent. I have not drove the car so it may have been installer error if the pin was already bent. I am just looking to not repeat mistakes.
