Hey, folks. First time posting here. I got a 66 Valiant with a 225 Slant Six. Any recommendations on a new radiator? RockAuto doesn't have any and I'm finding options on Amazon or eBay but, to be honest, I don't know how best to vet them. I'm basically a back yard mechanic with an engineering degree but not so much practical experience.
