Due to the difficulty of using the CIK specification numbers on Cadet bodywork we are modifying the requirement in Rulebook Section 20.2.2.1 to "at least 5" tall with a .750" stroke". The competition number shall be bordered by a yellow background of .375 minimum. No other modifications to the specification is allowed.
