Does anyone know where to get new door hinge pins and bushings? I havent had any luck finding them for my 63' 88.

 

You probably won't find a kit labeled for that car, but there are only a few different bushings and pins used by GM. Just measure the ones you have and buy the bushings and pins as needed. You can get longer pins if necessary and cut to fit. Dorman has a selection of different bushings and pins, for example. Clips and Fasteners is another possible source.
