I am looking at possibly buying a 65 GS 4 speed a/c car and I have some questions on the trim tag. It shows to be a flint(FB) car,with white(154) buckets,group 2 options klp , 4 spd,a/c and backup lights ? group 3 (H),which I can't seem to find , group 4 (s) ,GS.Also on the TR line ,after the 154 code , and under the FB code there is a 2 letter code "KC".can't seem to find any info on that either.I have had several 70 and 71 cars , but never a 65
