Fitment & Compatibility
The listed 1955–1957 Chevrolet applications require the specified CPP two-inch drop spindle, casting CP30102. This is not a stock-spindle conversion by model name alone. Listed Del Ray coverage is 1957 only; retain each other model's exact table range. Four-piston Dynalite calipers use BP-10 pads and 12.19 × 0.81-inch vented rotors. Aluminum hubs, bearings, seals and 1/2-20 studs are supplied, with 5 × 4.50 and 5 × 4.75-inch wheel patterns. Flexlines are separate; the 220-7699/220-8307 references must be selected for the actual fittings, steering travel and route. Check the supplied wheel drawing with the nominal 15-inch minimum guidance.
Listed models: Bel Air; Nomad; One-Fifty Series; Sedan Delivery; Two-Ten Series; Del Ray. See the supplied table below for each year, submodel and equipment condition.
