You should re-read my post, unmarked switches usually Cole-Hersee are correct and were supplied through GM. ARK LESS switches are not supplied with NOS heaters, nor is there any evidence they were supplied by the factory. I know you take great satisfaction in taking the opposite view from me in every post. At least do me the courtesy of reading and quoting me correctly. Things get foggy now some 70 years later, really you think?
