Cold Case Aluminum Radiator - 63-66

$400.00

1963-1966 Chevy/GMC Pickup Truck Aluminum Performance Radiator. For trucks with original 3 core mounts.

Also will fit some: 1961-1964 Grand Prix and 1961-1964 Bonneville/Catalina.

These COLD-CASE radiators are Tig welded 100 percent 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.
