Looking for a '72 duster radiator

Anyone have any ideas on where I could score a cheap radiator? I need something cheap while I get the engine rebuilt/tuned. I will buy a proper one once I get her road worthy. I know I can get it running w/o a radiator but I'd like one for setting her running just right. thanks guys

you can buy a new one at auto zone or advance around 150. lifetime warr. or i'll sell you one good one for 80.00 plus ride
