I was in the market for a replacement and was considering the aluminum until I came across an original one on Ebay that had been quad cored then the owner sold the truck. He paid well over three hundred to have the work done but I got it for $87.
Well, maybe I spoke too soon. The seller has yet to ship the radiator and has stopped communicating. If you ever come across cdunk907 selling anything avoid him like the plague! I canceled my payment and bought an aluminum replacement.
