I used it last year for 160hp Dynafocal mounted E3D into my PA18-135, just looked at the ICA and AML, includes the O-320 D2A and PA18A-135, from memory you pay for it on line and they email the STC through
Overall I found it very straight forward, it requires either Sensenich M74DM,74DM6 or McCauley 1A175GM Prop

Hey thanks Jim! Where did you get the mount? I was looking at the cubcrafters stc which allows it too, but they call out a CC part number for the mount. Problem is Vera told me they have never produced nor will they produce this part. The way I read the stc, this pretty much disallows any dynafocal Mount engine. Hoping Svenns was a bit better.
yes. he is providing us a great service by listing MANY suffixes of 320/360, dynafocal and conical etc on his STC, and also Ruppert has a reputation for fabrication of very nice parts.
