Hi John, mine only had a cotter pin pushed into the hole to retain the pin. Sorta figured that wasn't factory. ??
Don't see where to get between the frame and clevis as its welded to the side rail do you mean use the heel bar on the head where the grease fitting is?
Call me if you wish at your convenience at 248-789-4323 and I csn send a few pictures if I have to. Thanks again, Doug
