Thanks! I am working on a 1979, I need the defroster actuator, I see they sell the fresh air actuator which is mounted slightly different. Would require some drilling. But it could work. You mentioned the dual actuator, I had to dig to see mine, I do have one dual and of course only half of it was working. I found a good used one in my parts, hopefully it will last awhile. Another swap meet item to watch out for.
