they ARE identical. but, on a non dodge pump, some of them dont have the threaded bosses for the factory throttle linkage bolts, when i put my bus pump on i bought pipe plugs that fit into the threads on the pump (5/8 i believe) and tack welded a 7/16x1'' bolt on there and the throttle linkage bolted right on. i'll take a couple of pics and post em up so you guys can see how i did it
