1963-1966 Chevy/GMC Pickup Truck Aluminum Performance Radiator.

These COLD-CASE radiators are Tig welded 100% aluminum and absolutely beautiful.
Don't buy a 3 or 4 row aluminum radiator!   It doesn't cool as good as these oversize 2 row models.

These radiators are original appearing and have the correct stamping. Once painted, you'd be hard pressed to find a difference over an original versus a COLD-CASE.

Had to modify radiator mounts on truck to get radiator to fit because of the radiator tanks were wider than the original. Other than that it was a great product.
