I just ask because I pulled the z-pin without pulling the roller table. The replacement d-pins include the roller table as a soldered assembly with wire extension. I’ll have to find my roller table remover if so!!!D- and z-pins should be interchangeable. Z-pins were made of a harder metal than the gold alloy D-pins, and didn't wear as quickly.
No, I don't know where to get spare pins. That's why God gave us watch repair stores and watchmakers!
