Big Daddy does not know how lucky he is to ger one of your masterpieces!

I've had dragsters in the past and the steeering shaft from the butterfly to the rack is a hollow tube. With a bigger diameter you can use a thinner wall tube for less weight. They are supported 1/2 way down with a rose joint(heim joint). They appear to be simple chassis, but are complicated in engine height, distance to rear end, and angle for the best traction.
