I have a good news/bad news follow-up on this. In reading over the Confidential Bulletin announcing the Carolina, (#92, 3/20/53) It states "With the exception of transmission options, no other special equipment items or accessory groups are installed on the Kaiser Carolina in production". This is somewhat buried on page one in an area not associated with factory installed accessories.
However, in cases where medical need prevails, the club has followed a policy of not deducting points for equipment that reflects medical requirements. Also, there is no reason that I know of from a steering/suspension stand-point that would have a problem with power assisted steering. This however is only my own opinion and the Chief Judge should be consulted to verify what I have said.
