My good friend has a 1998 z24 2 door & the hinge pins on his drivers door are totally bad. I have replaced hinge pins before, but none so strange as these. It almost looks like I need to use an air chisel to chop off the tops of them then try to drag out the stubs on the bottom. The new pins & bushings look to be held in by the e-clips provided & the shape is flattened out on the other end of the pin. I cant get a drill bit on top of it due to the shape of the door. Does anyone know the tricks to do this job? I am doing this on his car asap & I don't want to screw anything up.
