Does anybody have or know anybody who has the rules and regs for VARA's A Sedan race group. National Auto Sports Assoc. (NASA) just started A.I.V. (American Iron Vintage) which allows A Sedans with VARA and other race orgainzation set-up's to compete. Im building a 66 fastback and need to know what is and is not allowed. Example: How radical can the roll cage be? What type of Rear Axles can be used? All that fun stuff. Any info would help greatly.
