Walker Radiator works a lot of swap meets. I think they are made by Champion. I have used one on a car an it has done very well. $200 bucks total for an aluminum delivered to my front door.....and comes with a very nice heavy radiator cap and overflow tube....bought it about a year ago. I'm almost sure they make a replacement for the AD pickup. There are other vendors.....just search radiators and get hours of reading!
