'56 PA22 - I have to shorten my cotter pins to get them into the 1.5" axle wheel retainer nut hole. The rim limits the length of the cotter pin. In order to get it in the hole, I have to shorten it so that it will line up straight. That results in very short little nubs protruding on the other side to be bent over. Very short. Like 1/4" at most. Are there any tricks to this to get a longer end out to fold over?
