So one of my roll pins came loose on my lower steering shaft this weekend and I lost all steering other than my feet pushing the tires to the left and right until I could park my 502. I was looking at the roll pin service bulletin here, wonder if using a 1/4-20 bolt with a smooth shaft might work. Has anyone tried it either way on an old horse? Would there be any interference of the bolt head or a lock-nut anywhere?
