My question is about the stock frame spec in the rulebook. Can you add different suspension to the stock perimeter frame? I have a 53 stude that has the original frame with an early ford straight axle added. Really want to run classic gas coupe with this car rather than altered. Since the original rails are intact, does the frame meet the spec in the book? How about adding mustang II rack and pinion? Both suspensions add a crossmember but keep original frame intact. Hoope someone can help with this.
