Thanks Mitch, I was able after much heat, penetrating oil, and beating, to drive the pin out. Whew that was a whole days worth of work. Now that I have the pin out and the the hinge half that was attached to the door off, I need to find someone that can drill out the old oblong over sized pin hole and re bush it back to the correct (.250") size. I suppose I need to find a machine shop near me for that ... Thanks again guys for stepping up.
