Okay, I misunderstood you about that. The pins gotta come out somehow. Somehow they were put in so they should come out. How about a drop of penetrating oil left on it for a few days? Not much to lose if you break the pin off and try to drill it out on a drill press for accuracy. I would also try tapping it kinda hard with a small hammer on the side of the pin for a while to get the penetrating oil to work it's way down in it.
