I watched the WCCC video on door glass adjustment on a 69, (a project I was in the middle of) I saw the rabbit trail of a loose door hinge and using this pin with a retainer and bushings. I knew it would not be as easy as Don made it out to be, but I recognized my own need for the same, so I order all the pieces. It was a little trouble removing the old pin, but the new one went in slick, almost as easy as the video! Thanks to WCCC for making the video and selling the components! I highly recommend it to fix a sagging door.
