I am using a Afco aluminum radiator in mine. It fits where the stock one was but not a direct bolt in replacement. The lower hose outlet is different and the core is thicker. You also need to make your own side plates (flat aluminum) to mount it to. I slide mine forward till it hit the lower chin sheet metal. I may go back and cut 1/2" from the stock sheet metal and move it even farther forward, I all ready have removed the cross support. It cools great and if it was painted black, you wouldn't know it was different.
