I just picked up the Motorsport 3-row radiator. Looks good, haven't bolted it on yet, but it looks fine. The 3-row gives you more cooling power. It looks the same as the stock 2-row, except on this one the little metal shroud has a slight ridge versus a smooth arc.
I got a 3 row from AAA Radiator in San Marcos, they are a wholesaler to alot of the autoparts stores in San Diego. It was about 2/3s the price of the MSA radiator, and it was in stock. It works great, and we get alot of 90-100 deg days here.
