Does anyone know how to remove this pin? It is located in the legs of sideswipe.

That's one of those hard ones..There's a trick, with a soddering iron, you touch it, tip to the pin, for about 10-15 secs and it starts to heat the plastic around it, and you can pull it through..I've done those a couple times..And always hated that I ever bothered. I'd just tape whatever you need off, and work around it.
