6972 CORVETTE SB CF

This radiator is part of the DeWitts Modified Pro-Series for LSX engine conversions in 1969-72 Corvettes. It's designed to fit the original small block (pin mount) core support. It incorporates a filler neck for a direct-mounted radiator cap, eliminating the need for a separate surge tank, and includes a connection for the steam line. This design also eliminates the stock upper mounting bracket. The 'A' suffix in the MPN likely indicates compatibility with automatic transmissions, and potentially for cars with air conditioning and/or higher horsepower, differentiating it from the 'M' (manual transmission) variant (32-3139070M).
