best ones that i have used are the champion radiators that are sold on ebay. i got the 26 inch for my scamp, with two fans shipped to my door for 260.00
I know, I've heard of those...Was thinking of using them but not sure...I can't remember if that was the brand I saw at the fall fling last month, but to me the welds looked cheesy...Not sure if it was champion or not...
Also, do they have the built in tranny cooler at the bottom?
