I have a unindentified brand of IC coil car that came to me in bad shape. I'm currently putting metal wheel sets and new Kadee couplers on it. I recieved the coil car with one truck detached and missing the pin that attaches it to the bottom of the frieght car. What are these pins called? Or should I replace it with a screw?
Also does anyone know who made this model?
