There are some threads on this. I removed a couple relatively recently. Others will chime in for sure. IIRC, grab the pin with a vice grip, in a manner that will close the gap in the pin a bit. Then slip a lever, screwdriver or tire iron under the vice grip to pry up. Wiggle the vice grip while prying up gently and it will come right out. Move the VG down to get a better grip, and to close the pin a little with each rise.
PS: for powder coating you could probably leave it in, if the PC tech is OK with that.
