Excellent quality, not inexpensive but you certainly get what you pay for. They will build to your spec. Made in Michigan and owner (Mark) is a car guy (Pontiac GTO). This is what I have and am very pleased. They also offer color anodizing of the radiator if that is something you desire. Talk to Fred for he will take good care of you.
