A friend of mine has a 64 C 10 and used a set of 65 K-10's on it, he had to do a little cussing to get them right, but he made them work. I'd assume that if the brackets from a 65 K 10 will fit the 64 C 10, then they reverse SHOULD be true. You may have to use a few four letter words to make them work tho.... :-)
