s10 door pin stops

on 94-03 s10 doors there is a pin that goes on the upper hinge that serves as a guide for the door to only open up to a certain degree, what is that called and where can you buy new ones? it is no the pin that connects the hinge, it would still be attached to the body after you have taken the door off. it has a roller on the bottom side of it where a bracket that is attached to the door rides along. anybody know?
