It appears to just be two bolts but I'd hate to unbolt those and
discover it's attached somehow inside the door panel. From what I can
tell from the diagrams, though, it's its own unit. I'll give the
wrecker a call and see what they've got for me.

When I go to replace the pin, how do you make it stay in? Do you need
to flare the ends somehow?

Cheers,

Isaac
