I founded Muscle Car Research LLC in 2006. It is a small, family-owned business located in northern Virginia (USA) that's focused on providing parts and services for the American muscle car hobbyist. My first goal for the business was to help me sell off the many parts I had left after restoring my 1970 Ford Mustang Mach 1, but it is now growing into a niche producer of parts for American muscle cars. I'm currently working on reproducing parts for 1969 and 1970 Mustangs that aren't available anywhere else.
