Fabco shoulder pin 12577829 is a genuine Fabco pin. A shoulder pin is turned with a step in it, so one diameter locates in the bore and the larger diameter sets how deep the pin can go and how much the part riding on it is allowed to float. That step is the whole function of the pin, and it is why a pin that looks close is rarely close enough. Order the 12577829 by number. Pro Gear and Transmission sells it as a genuine Fabco part, and a quick phone call will confirm it against your breakdown.
