if you were to weld that 1/4" plate floor to the top of the chassis, just try to rack it then. it would take one hell of a whack to do that, and there would be more important things to worry about , such as the health of the occupants. my state uses the nsra specs for streetrod inspection, and the asa testing can just be a "bought" deal if you know how to take a standardized test. lots of those jokers working at the dealerships around here that can't fix anything in 4 or 5 attempts. not saying all asa certed techs are nimrods, but there are sure a bunch of 'em that are. happy holidays.
