Just wanted to share if anyone is wanting to do the same thing. I have been having some lackluster cooling performance and decided to change out the old radiator. The fan would scream in these 95-99 degree temps. The old radiator was a 1 1/4" single row I think. I suspect it had some fouling. I found a 2 3/16" radiator at Advanced Auto for $249, part number 431334. With the current 20% off coupon it was $200. About the same price as if I ordered one from Rock Auto. The thicker radiator was a drop in replacement and seems to work a lot better. The fan isn't roaring when I take off anymore and the temps do not climb much while stopped. I do plan to change to a heavy duty or severe duty fan clutch as well.
