In my other life, I do a lot of classic car repair work on the weekends. It's always tricky to find the right parts for the older Chevys and Corvettes. I especially have been intrigued by a radiator source a buddy of mine uses. He's trying Entropy Radiatior - so I've ordered a new retro radiator from them. I'll keep you posted on how it fits into the Chevelle I'm working on.
