Replace your cracked or missing fan shroud with an OER? reproduction! All fan shrouds will mount correctly to any original GM radiator. Aftermarket reproduction radiators may not include the correct fan shroud mounting brackets which will make it difficult to install your new fan shroud. All Classic Industries reproduction radiators are manufactured with the correct lower bracketry for fan shroud mounting. Be sure to check your radiator and determine if the fan shroud mounting brackets are correct for your installation. This will eliminate problems which may lead you to believe the fan shroud is incorrect upon installation.
