Mike Ring of the Ring Brothers brings by the "Producer" Mustang fastback and the "Diversion" Camaro. He talks with Adam and Matt about the challenges of building custom resto-rods. We hear about sourcing parts, meeting SEMA deadlines, the ups and downs of customer tastes and trying to stay profitable. The Ring Brothers were back-to-back winners of the Good Guys Street Machine of the Year award, and were also the Car Craft magazine Pro Builder of the Year for 2011.
