here they started in april of '68, called ke10
69 that continued with the sprinter (ke15), and the wagon (ke16)
then in aug of '69 the changed the side markers (bigger), the front markers (bigger), added the 3kc and acccompaning 1200 badge and changed the model no. to ke11 (i think), ke17(sprinter), and ke18(wagon, also known as daisy)
they only continued the ke1x series until 4/70; daisy is actually a '70 model, but since the parts books don't recognize the ke1x i list her as a '69 since she was born 11/69
of course that was just here.....we didn't get the 4door until '71
