I recently had 2 66 GS's here,both real GS's one i bought another a friend bought. It had a code on the trim tag i have never seen before, does anyone know what this insignia mean & it was on both in the lower right part of the tag. I cant find any info on it. One was a bucket auto on the column with manual brakes and steer, the other was a 4 speed convert, both are gone, but i am curious. Thanks in advance...mark
