Need to replace the hinge pins on these big-ol doors but can't find the one with the roller that the little arm glides across when you open and close the door.Am I looking for the right thing and if I am ,where can I find 2?

 

I think your only option might be scavaging from a junkyard. I know you can get the generic hinge pins at the auto parts stores but those little cams......I don't know.
