This it our heavy duty all aluminum radiator for the 1968 – 1977 Pontiac Lemans/GTO that use the 28-1/4" wide core radiator. If you’re sick of getting Chevy left overs for your Pontiac then this is the radiator you need. Usually A-body GM radiators are universal fits. What that means is for your Pontiac engine, it usually comes with hose adapters and a bunch of extra fittings and plugs on the radiator.
Extra stuff you don’t need and hose adapters = UGLY.
