About Auto Metal Direct

Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective!  Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service. 

Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
