From a MB small truck, needed replacement of the mountholes only... 4 on the MB, 3 on Chevy. ( 6 rib type)
But not quite sure this was for the crank, or waterpump & other accessory.(said to on a crank...) Also took the pulley from the alternator, if i needed it...(Bosch type, similar as on my car from before, and that i changed pulley on some years ago to V-belt...)
