Matching fan shroud

Pair your radiator with Fast Monty's Garage dual 14-inch fan shroud for Cold Case GMA42. The shroud listing names GMA42, GMA42B, GMA42A and GMA42AB, with raw aluminum or matte black options. Shroud sold separately; fans are not included. Review fan compatibility and installation requirements in the shroud listing.

Fitment notes

Confirm the application for your selected part before ordering. The GMA42AB supplier description lists 1968–1977 in its opening paragraph but 1968–1972 in its direct-fitment notes; that range requires confirmation. For an Oldsmobile 442 requiring a 28-inch core, the black-version descriptions direct buyers to GMA43AB instead.

Legacy part number listed for both polished versions: RPE44L.

Warranty: Limited Lifetime Warranty.
