My boss has a 99 3500 4X4 he uses to pull his 3 car trailer. Last week the clutck blew up and no longer will disengage. He is needing to find a clutch that will haul 3 cars and take the torque of the PM3. He is also in the market for some 275 hp injectors. Any help would be appreciated on finding the best deal for these 2 parts.
