From the information i have in front of me - It is the STC #SA315CH issued to McCauley for the Mooney models M20A, B,C,D,E,F, AND G. It shows that this prop can be installed on the 0-360-A1D, 0-360 A1A, and IO-360-A1A. I'm not a A&P mechanic but this STC will go with the prop and I believe all you would need is maybe a form 337 filled out by the installer who bolts it on. Existing governor should work just fine. Hope this helps. I can send more detailed photos if you need them and copies of the STC, log book, etc.
