1977-1987 Chevy/GMC Pickup Truck 19" High Aluminum Performance Radiator. AT Cars. For taller 21" version, see GMT556A-21.
Upper Hose 1.5" and Lower Hose 1.75". For other configuration, see GMT556A-1

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.

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.
