This is a cropped scan of a Ford/Mercury Master Parts Catalog (MPC) page listing rear axle housing assemblies (basic part number 4010) and their related hardware for 1967–1969 vehicles. The table cross-references axle identification tag codes to service part numbers: 1967/68 axle codes WES and WFD (built before 4/1/68) use housing C7ZZ 4010-F; 1968-and-later codes WES, WFB, WFD (from 4/1/68) use C8ZZ 4010-A; 1968 codes WCZ and WDJ use C7ZZ 4010-E; and 1969 code WGA uses C9SZ 4010-A. All housings are listed "without carrier." Below the housing listings is attaching and sealing hardware with standard-part numbers and quantities: ten 3/8"-24 lock nuts (34445-S(M80)) and ten 3/8" flat brass washers (373820-S(XX155A)) for housing-to-carrier attachment, a 1/2"-14 hex countersunk pipe plug (87675-S(P17)), a 3/4"-14 square countersunk pipe plug (358048-S(PP43)), a 7/8" flat plug-sealing washer (352733-S100(XX247)), and a 7/8"-18 hex head plug (379166-S(PP54N)).
