Ok, since you guys seem to have no knowledge on this subject, I'm going to try drilling out the old hinge pin this weekend and replacing with new pins and bushings. I'll let you know if I'm successful. By the way, I went to the chevy dealer yesterday to ask again about the parts, and they told me that the hinges and were no longer available, even if you wanted to cut the old spot welds and weld on new hinges.
