To answer my own question (and in case someone stumbles upon this thread): The larger Parker Hannifin (Cleveland) assembly 30-65 includes two O-Rings 101-02700 (MS28775-222).

That's what I thought. But Cleveland parts have longer numbers, including 101-27000, 101-27200, 101-27300, and 101-27900. So there is still ambiguity.

Can't seem to find an O-Ring with the Mooney part number "101-27" - even though it should be an easy part to find...

Two of my Wemac vents are not functioning. Borescope shows that the body that holds them apparently came undone from the headliner - I can look behind the headliner with a camera, rather than just into the air hose as in those vents that work properly. Saw several posts with regard to the vents, but it seems my question may have been too simple to even address: How do you remove (or at least lower) the headliner to get access to the vents? There don't seem to be any fasteners...

If the Moritz gauges work I might be interested...

Interested.

Certainly priced for people other than me... even though I suspect there aren't that many.

Looks awesome. How much are you asking?

Sounds awesome. Definitely interested!

Looking to buy an airplane, and a Mooney 201 seems to fit the mission. Never flown one though. Anyone in SE Michigan (PTK, VLL, DET) who can help change that?
