The bar on my driver's door stop (technically, the "arrestor") broke. I happened to have a spare arrestor, so I thought this would be a relatively easy "remove the broken, replace with the new". Well, of course, that was not meant to be. The part of the arrestor thats on (in) the door is mounted with two triple-square bolts that pass through sheet metal of the door. Well, it appears that this has been a long-simmering breakage. The door sheet metal on which the arrestor mounts is broken off from the door. So, even if I could remove the old arrestor, there's nothing left on which to mount the new one.
I'm open to suggestions.
