I have zero experience with jail bar trucks, you da man for that. Pretty sure though cars from 39 up use 3 bolts. I would have to go out to the frozen junk in the barn to verify, but going from memory they use 3 so you cant put the wrong one on the wrong side. Cant say off hand, is it only 3 holes are drilled and tapped, I forget...irrelevant if your truck had 4. I'll shut up now...carry on GB
