A/C Heat control vacuum actuators.

Anyone have a good source for new vacuum cans that are used in the under dash A/C Heater box.
How about part numbers for them?

Thanks!

Try https://www.oldairproducts.com/ They have the single inlet ones, maybe (you did not give the year). The dual inlet one is real hard to find.

No idea on GM part numbers.

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.
