There are a number of different props that can be used on the various Lyc 540 engines on the Maule's and the spinners have different diameters and shapes.
McCauley 2 and 3 blade, Hartzell 2 and 3 blade, MT 2 and 3 blade.

True.. I’ve installed an hartzell 3 blades. A friend got me a metal spinner that looks awesome but also gigantic. Since I’m restoring the cowlings right now I cannot try and fit. The diameter is 15in. If placed above the upper cowling it follows the same curve which is encouraging.

I'd say custom fit it for best airflow for engine cooling. The Maule cowling top front sometimes matched up well and other times was off to the side, sometimes too high sometimes too low. Depended on how the cowling was fitted at firewall but taking into account clearances of mufflers, alternate air tube, air intake, side baffles, alternater bracket, starter etc.
The later Maule cowling top front was more generic and allowed for misalignment with the various spinners.

They should be XAG-3TM-3 e XAW-3TM-3, from aurora bearing.

I had contacted the dealer in the past, hoping to save money, in the end I bought them from maule as they were cheaper and readily available.

Thanks freedom. I was looking for an alternative but nothing changed, I got the same result. Very difficult and even more expensive to buy an alternative of these rod end bearings especially the left hand threaded. I ordered them from Maule.

Bolt bottom pin to tab.
Place tab in position on rudder, with bottom pin in mount hole in rudder.
Place top pin inside tab, slid down so the top of the pin is flush with the top of the tab.
Hold pin in this position by squeezing sides of tab so as to pinch the pin.
Position tab so pin is lined up with upper mount hole.
Using a hook tool, safety wire, coat hanger, or equivalent, raise top pin into position, and install mounting screws.

Don’t forget the bushings that go in the mount holes.
