Charlie,
The Gale Banks S-15 Sonoma was an interesting first link. I talked to Gale at the 2007 SEMA show and we talked about the wind tunnel testing he did for the tail gate and bed cover research. We talked about the 57 and he gave me some ideas to try.
This was a first generation S-10/S-15 and it was a little "boxy". They were actually running it in a car class which is available to pickups, but not usually the best choice.
I say all that to say this. The new land speed race car I am building is a 1998 GMC S-15 extended cab pickup. I wouldn't say Gale was an inspiration for this, but I am hoping this second generation model will be quite a bit more aerodynamic. You might ask why I am not using a Ranger, and the answer is this pickup was given to me by a friend and the budget just wouldn't allow the purchase of another car.
I will start a new thread to show the progress soon.............
