Re: Cracked Off Front Fender Bolt - 1968
Update: Before attempting to cut the nut out, I decided to try some additional boring methods to dig into that broken extractor. I read about a thing called a Rescue Bit. Cheap it is not, but it did very slowly dig into that hardened steel extractor. I found that by using an alternating combination of the Rescue bit, Dremel 953, and Dremel 453... it chewed through the extractor more quickly. In all it took about 2 hours to get through the 3/4" of extractor that was wedged in the bolt hole.
So what I am left with now, is a somewhat "cone-ified" tunnel into the nut. So not a perfect cylinder hole anymore. As far as I can tell, if I tried to retap the hole for the 3/8 OEM bolt, I might be able to get 2 or 3 correct depth threads toward the end the nut.
So would my best approach be to drill and tap it for a 1/2" bolt instead, to increase the number of good threads I could make ?
