Radiatorbarn.com has Cherokee radiators for good prices. They have a 2-row I've used for $190. It's all metal, not plastic and aluminum. They also have an all-metal 3-row for $222, but that seems like overkill.
So a two or three row helps cool it down faster... I'm looking for something good for a trail rig... not too worried about the price aslong as I don't havta worry about it running hot
