Rat Rods are hot! So, Joe and Mike explore the lifestyle and go on a mission to find the perfect Rat Rod body for our "Raunchy Rat". First, they visit the annual Street Rod Nationals in search of a chassis for their '29 roadster Rat Rod body. Then, back at the shop they load it with suspension, brakes and a steering box. After that, they show you how to channel the body to make it ride right on the frame before building and installing a vintage Ford Flathead motor, supercharger and transmission as Raunchy Rat gets closer to completion.

Then Joe and Mike finish the brakes and clutch, also creating a floorboard with road signs, installing some off-the-wall seats and finishing touches. A rat rod is never finished, so it seems. However, Joe and Mike finally put the finishing touches on their '29 Ford before Mike takes it to a local car show to blow people's minds.
