Got my raised steering arm on. Needed to file the edge of a messed up threead on one of the studs. Cleaned, and sat the arm on. Cleaned, and sat the conical washers in place. Then started the lock nuts. Using a 1/2" drive ratchet I ran the nuts down. Got them as tight as I could with just the ratchet and switched to a technique of hitting the steering arm with a hammer, and using a 4' piece of DOM other the ratchet to tighten them. Worked like a charm.
