I think I bought my pins right off the floor display at napa, must be a common size. I used oilite bushings instead of the plastic bushings. It was all pretty simple. NOW!! The ball buster for me was, (and still is) is the door alignment. Man!! I have tried every combo with the upper and lower hinges and cant get it right. If Im good for the door to quarter gap Im way off for a parallel gap at the bottom at the rocker. And at this point Im just looking for a parallel gap at both sides, Ill tackle a new road when I mount the front fenders but they are a lil more forgiving. And I could swear they were looking ok before I removed the door. ERRR!!! So Ive spent days moving the doors around. And I read all the posts about re-aligning the doors. Im just chasing my tail at this point. Kinda wish I would have left the hinges alone at this point. JR
