I just got a free set of bumperettes to fang tooth the 83'. Had to sheer off two of the bottom bolts. I'm going to need a professional to help me install them on the 83' unless someone can help. Looks like I need to sheer off all the bolts and custom cut the correct bolts and double nut on the back side? Any other ideas without welding equipment? Had to jack some stuff up, they were on a 78 bumper and did the best I could to get them off. They're in great shape though.
