Any Salvage have older Cummins parts---1987 855 Cubic 300 HP Balancer??

Have a 87 Pete with the 300 Cummins. Today the pulley on the back of the Vib balancer broke a circle around where it is press on. Sounded like a pie pan flopping around on there. I would like to find a good used one if possible. Most of todays suppliers are not going to have 30 yr old stuff. My neighbor who does alot of Cummins work said he never seen one break like that before. Anyone have a lead? Thanks, LB
