1) I had broken the lower bolt of the bumper guard of my 71 Vette. I can't remove the broken part in the bumper guard although I used an extractor. So I think I will rebuild the thread with a helicoil :
Can you confirm a 7/16 SAE is correct for these bolts ?
2) The 2 little front bolts of the passenger headlight bezel were replaced by 2 screws that damaged the original thread (see photo). I will restore the threads with helicoils. In this case, I don't know the correct size. Can you tell me please ?
