The Stovebolt Site Forums The Parking Lot Big Bolts need help with part# for dog bone master cylinder

found a master cylinder on e bay, looks exactally like the one on my truck, but I cannot cross refrance the part # to my application,neither can the seller just says 1970-1973 chevy and 1967-78 gmc truck. I have a ( 1970 C50 truck ) Can any one help? here are the part #'s listed in ebay- ac delco 18m52,carquest E150193,napa 36467,bendix 11618,wagner f77034. It has been called the dog bone type, and is a 1-3/4 bore. Will it fit my 1970 C50 dump???

Hy rust master, my United catalog shows 36467 to be for a 1973-83 CE,CG,CM,CS,SE,SG,SM,SS,50 series with Wagner FF52750 with dual brakes. Does your truck have a dual or single system? If it is a dual system, this master may "fit", but it has more capacity than required, so your pedal stroke could end up being much shorter to get the truck stopped [ touchy pedal ], hope that helps.

Yes I have duel brakes ( 2 hydrovac units under cab one front and one for the rear)
