I am in the process of rebuilding all my door, hood etc. hinges. Once taken apart hit the parts stores, Lordco, Napa etc. They should have a selection of various brass door bushings and stainless pins. I picked up a bunch that were the closest to what I needed then simply drilled the holes in the hinge to accept the new bushing. They are very much stronger than the nylon ones and immediately available should you need to replace, although I doubt they will need replacing. Couple of dabs of synthetic grease and good to go. Tighter than nylon and bullet proof. As to the front bib hinge I did the same thing. Pulled the old pin actually used the special tool all of us that work on cruisers have. "BFH" Same stores have a good selection of brass bushings, various thickness and diameter of opening. Picked the ones I needed I think 7/16's drilled the hinge, grade 8 bolt and I'm good to go for life. and no more seized hinges.
