Not sure what you mean by one and two pin....but if you mean the sunvisor bushing tips...OPG sells them as a pair and they fit 64-77, so I would assume they is no difference..
Try the Sun Visor Bushing Tip Set under OPG's online catalog if that is what you are looking for. It comes with the tips and nylon sleeves.
