The Rastetter car had a chassis built by Don Hardy from Floydada, Texas (He also built the chassis for Kelly Chadwick's funny cars and some of the Gapp & Roush Pro Stocks) ............. all the pedals and equipment were attached directly to the chassis tubes ............ the aluminum floor bolted to the bottom of the chassis tubes (very much like the floor of a dragster or funny car chassis) ............. I can't tell you about the fuel altered situations, but the Rastetter car didn't throw that much rubber and almost none of what it did made it into the drivers compartment ............ most of the debris which got thrown was fired out behind the car as there really wasn't any body behind the slicks............ almost never had to clean the 9" Ford rear end .......... other than a small burnout, you didn't want that car spinning the slicks at all ..........
