1965-1966 Buick Gran Sport without AC Aluminum Performance Radiator. Cars with AC had curved upper inlet.

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.
