Well, my radiator's got multiple cracks in the plastic tanks on both sides. I did some looking around and found some aftermarket plastic-tanked radiators for around the $500 mark (and a few sketchy ebay/etc. ones for around $200). Does anyone make an all aluminum radiator for these, or are there any better options than paying $500 for a plastic one? I plan to contact Griffin Performance to get a quote on having them build me a custom one, but just wanted to check with you guys first to see if there was an easier (or potentially cheaper) option.
