a lot of folks like the rad from PB's (i assume you mean the 3 core Modine or Go Dan that they sell). does it not have a lifetime warranty?
try a search - there are tons of these threads (some even have the same title i think). there was one yesterday with 2 pages.
Well it was the direct replacment for the stock radiator.. at the time i just bought it cuz it was $80.. Had to replace my motorsport 3 core rad since my balancer blew off the crank and went through the rad lol what a sight lol it might be lifetime warranty now that you said that.. i'll go back to the store and find out
