Daron,
I just had to look through all the options we have radiator wise. I could find only one direct replacement from Griffin, but it's very pricey, close to a grand. I'm sure Mike can get you one if you want it. BeCool also has a radiator for us without the engine oil cooler. It's around $500, but you have to fabricate your own oil cooling setup. Beside this it's a direct replacement too... Both of these are two row alu radiators.
With more fabrication you can make fit one of the general alu radiators from Howe, BeCool, Griffin or even Summit. Their prices are from $200 to $500. The problem with them, that our radiator is 31"x16.5", or something like this. Most of the general units are either 16X27 or 19x31. I'm not sure the smaller ones will give you the performance you want and you can't fit the larger one without cutting up/replace the radiator support. You also have to fabricate your own tranny and engine oil cooler with the general units.
One more though. If you go to the custom way, it's a great idea to remove the tranny cooler lines and put the tranny cooler under the bed in the back. This came from BG, but Jesse (HuRyde) has a similar setup too, if I'm right.
BTW, that was too messy for me, so finally I ended up buying a factory radiator. That's it.
HTH,
