I too would like to know I just got through working with a buddy on a 24 valve daulie he bought that was cursed with a Fram filter and had some bearings wiped out as well as a gaulded piston, We had to buy from the local Cummins dealer because everbody we talked to said there was no aftermarket parts, a piston cost me $160. I just bought a 95 with a knock and pulled the engine out and need parts to overhaul it. I will keep looking.
