McCauley makes two hubs that fit the Lyc flange I recall. One is longer and what Whirlwind uses on their two bladed model's. There's a shorter version hub, which is more common and most likely to be found on the used market. The problem as was mentioned with the short hub is the spinner is made to mount off the flywheel, so you have to make extensions, brackets and back plate.
I am no McCauley or Whirlwind expert, but Whirlwind uses McCauley hubs. The WW200RV has all spinner parts, plus cool composite blades. If you want to avoid a Hartzell BA than a good 2nd choice is the WW200RV prop. The big diff between the two hubs is Hartzell has a split hub retention, bolts and all that stuff.
If you go new from McCauley it will be the most expensive prop you can buy, probably more than a Whirlwind. I am not sure what hub you can find on the used market, but its most likely for the Mooney 201.
McCauley had resonance limits as well, as much or more than the Hartzell. McCauley has done no flight test with Electronic Ignition, which aggravates the resonance issue, as Hartzell found. I suspect the McCauley is affected the same, but it is an unknown. I think McCauley was certified on counterweight cranks, but you need to research that. Putting it on a non-counterweight crank with Elect Ign may be an issue. I guess some DAR's might have heartburn with a McCauley on a non-weighed crank:
