My 56 uses 74 Camaro style calipers & hoses and my 55 uses 85 Cutlass hoses & calipers. 98% of the systems out there use one of these. Take your old parts to NAPA and give them those choices. The only car I have ever seen that used the same hose disk or drum on the ft is a 67 SS350 Camaro. The 4 piston caliper has a short steel line between caliper & hose.
