1977-1987 Chevy/GMC Pickup Truck Aluminum Performance Radiator. AT Cars. 19 Inch high overall. For 21 inch high version, see GMT556A21.

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.
