Go to your local parts store in Help section and get a GM door pin bushing kit 38400 and drill out the holes tight to accept the bushing, cut the pin down to length. I always do mine like this without any failures yet. Drill thru both holes at the same time and the holes are aligned. Every does make a big deal out of nothing. Cost about 5 bucks per hinge and spares readily available. Mine were 71 and 72 Road Runners (heavy long doors). Rebuild was better than factory equipped. Now if you think it's not as delivered from factory, it's probably not for you.
