picked up a frame over the weekend. has a crankcase adjust bolt that goes through the back motor mount stuck in the frame. was able to remove one of them with an impact gun. no thread stripping, just most likely seized on there from heat and time sitting. the outbound side where you'd use a 19mm socket after removing the castle nut was already stripped from the shop that disassembled the bike. the inside of the bolt stripped on me last night with a 12mm hex bit. i've used heat. i took a grinder off to the edge and tried with a big ass pipe wrench. it's really stuck in there. guessing the outbound side might have been peened a bit and now is stuck.
so where can i bring this to get extracted? i'm in the south shore.
here are some pics of the bolt, so you get an idea
