Thanks for info guys, the lugs nuts were inclosed long gorilla brand ones. I'll go and get some open ended ones and trim off the bad part like you said
i can't recommend this, as then your studs may be too short to use with your new wheels. i would replace all the studs. if you look close, your pic shows thread damage below the really buggered up portion [the shiny three or so threads]. these threads are deformed, and i wouldn't trust 'em. i know that may not be what you would want to hear, but 20 studs would be WAY cheaper than a crashed truck. just my opinion, and repairing threads in many things over 50+ years.
