1995 Tahoe rear door removal -help

does anyone know how to remove the rear doors (barn door style) on a 1995 chevy tahoe. the hinges are permanently attached to the body and the door. So I would assume you could just take the pin out of the hinge. however, the pin doesn't seem to want to come out. I thought maybe i should find out for sure before i break something.

come on...I know somebody has taken these off before

they are a pain in the ass to knock out i did at a shop i worked at one time tried a punch and a big hammer then an airchisel a real big pain

yeah i beat on mine forever and it didn't even move. there is a set at the junkyard I want to pick up to replace mine with, but i need to figure out how to get them off at the yard.

wd40 and a biiiiiig hammer and a flat punch
