Trans cooler recommendations........

I plan on running this one from Derale.

This one has 1/2 tube and -8 inputs but you can get them with -6 fittings. They have several core sizes and Derale also makes plate type. I don't think I'd screw with an ebay one when you can get such good quality for $60.
