First gen kickdown/detent cable help please
 

The throttle end of the kickdown cable in my 1990 d350 Cummins has come off and I can't find another cable that will work. The cable is still intact it's just missing the metal slide that hooks on to the pin on the throttle cam/arm and i haven't the slightest clue where it went . I need to find either the metal end and hope I can attach it to the cable or a whole new cable. I have been searching online and at junkyards but these are hard trucks to find and I'm pretty sure that part is discontinued. Any help would be greatly appreciated. Such a small and simple part yet Soo dang hard to find.
