I know this is a ford forum but I cant seem to find the info.i have some nors king pin sets and my 41 linc conv. needs king pins.i have no way to look up the numbers on the boxes.could some one tell me the king pin size on a 41 Lincoln so at least ican see if I might have the correct one?i don't want it torn down and have to wait to get some if I don't have the right ones.they want 350.00 -400.00 bucks for a linc. set.thanks in advance.
