I am trying to fine some information on a '68 Chrysler model 6018 6.6 hp water pump housing. The drive shaft to the lower unit was seized and I had to destroy the water pump housing to get the lower off. The housing that came off [ part # 144060] had 3 bolts, that held it to the lower unit. Does anyone know if a 4 bolt housing and wear plate could be used instead? perhaps a part # [the 4 bolt ones are easier to find] Thanks
