best cure for mangled lower control arm bolt holes
im workin on my buddys 57 chevy belair.

doing a full caltek suspension package.

on the drivers side lower control arm, one of the bolts on the stock control arm, almost pulled thru the frame.

i didnt notice, until i put the new tubular arm on, and theres a significant gap inbetween the frame and control arm, the bolt (new 7/16-fine, grade 8) would not pull it together. i tried tightening it but to only de-thread the bolt. same with a 7/16 corse thread bolt.

my oxy is gone so heat is out of the question for a sunday.

i could cut it out, or grinding it, but this will weaken the frame.

what would you do?????

thanks guys!

I can't see it but obviously welding it is what SHOULD be done, repairing it properly. There are some gray areas that I don't want to even suggest.

If you posted some photos maybe it would be a lot clearer and something could be done but right now, broken frame, control arm mount broken out? Weld it properly.

the bolt didnt pull through all the way, i got off my behind, filled the tanks, heated it up,bent it back, and put an extra thick washer on it and welded it up.
shes golden now :thumbup:
