I got mine from this guy.
eBay Motors: 1994-2001 94 01 Dodge ram Truck door hinge pins pin (item 200211986864 end time Apr-05-08 17:22:34 PDT)
I lifted the weight off the hinges with an engine hoist. The wires into the door have the connectors inside the rubber boot, disconnect there. Mark the hinge locations on the door and remove the bolts that go into the door, not into the door frame. Once the door is off the hinges are easy to access. Drive the old pins out (make sure to remember how the spring and bar are installed in the top hinge) A little drilling/filing may be needed for the new pins. Drill sizes are on the instructions. Assemble the hinges and remount the door. It took awhile to do the first one, but I could do it in less than an hour per door now.
