Dave,
Nobody knows what a rat rod is. Horsepower TV is building a "rat," but the only thing on it that's even mildly ratty is the body. They used a complete P&J frame with a Super Bell axle, chrome coil overs, chrome hairpins, disk brakes, P&J ladder bars and panhard bars, Vega box, yadda, yadda, yadda.
Standard street rod so far.
