The two links below are a step by step process by Doug on how to build up an A/FX TCP Pan Car.
In Doug's words: "This is the basis for the cars that Nelson and I ran at our first Michigan Gravity Race earlier ( in 2011) and they were very competitive. This article shows a very basic stock type build up, our race cars had modifications not covered in this write up, mainly being brush tubes and modern front and rear tires."
