I just came in. I borrowed dad's angle grinder (which is at least as old as the 1980's) and ground the head off the free wheeling carriage bolt (core support).
I first tried my Dremel Tool but it was way out of its league.
Then I met my match: a stuck inner fender bolt that I'll have to cut out. Too much rust in that inner fender. I'll cut that away tomorrow (with the Dremel Tool) and remove the old core support.
