It may depend on what pins you have. My 87 had roll pins, and they were pretty easy to punch out with an appropriate sized punch. I'm not sure how the later solid pins go though.
It's a lot easier to get at things if you take the door off the hinges first.
By the way, if you have roll pins and want to replace them, standard 1/4 inch ones will work. Tractor places have them in bins.
