For what is worth, I've contracted with Fred @ Mark 7 Radiators in Bay City, MI to fabricate a unit for my 572 Hemi challenger. He's done a ton of these and for customers like 'Big Hemi Customs'. I also feel I need to keep business in Michigan as much as possible since I live here. Although I don't have the unit yet, it should be done and ready for me to pick up next week. I can't wait! scott
