I have used a piece of bent up 1 1/2" wide flat bar with a 11/16" hole drilled in one end. Use painters tape to tape the clip to the bar centered over the hole. Reach in and lever the clip on over the pin then pull the bar off. I have the other end of the bar ground down to slip the clip off the pin and remove the hinge. Not my idea but a body shop buddy at the MOPAR dealership from years ago. dan
