I think I still have the original vents that I took out of my '74 Overlander if you're interested in keeping them original. I replaced them with Fantastic Fans. In the second post to the thread linked here there is information on an alternative way to upgrade the original vents using a radiator fan.

Airstream part number: 092 1105 roof vent cap.

Price = $38 in 2001

Vent opening on roof = 13 3/4" (outside dimension)

plastic cap = 14 1/8" (inside dimension)

Dimensions are pretty close. I measured from inside. Difficult to measure.

This entire cap is plastic. I replaced mine in 2001. No problems ever since.

These caps are Airstream and are universal "blanks." You hafta drill your own holes and supply your own rivets. I used garden variety rivets and good quality silicone sealant.

I hope this helps.

I'm following that model. One thing. I believe we should prefer poly caulk to silicone on our metals. While most silicone now has latex in it, that's the only way it is acceptable to metal. Read the 100% silicone application. No metal. It still works. Poly is preferred.
