Not sure how familiar you are with the documentation. Here is a brief summary of the process. Apologies if you already know all this.
First, you must have the IPC for your airplane (Illustrated Parts Catalog). Here is one for an M20G in the Downloads area of MooneySpace, but you will need to be sure it covers the correct year and serial number for your airplane. Usually serial number is more important than year -- Mooney changed things more frequently than once per year.

As an example of how to find a part, in the illustration on page 142 (PDF page 134) one of the rod ends is numbered "29". In the list following the illustration, "29" is identified as p/n F34-14 which looks like an oem p/n and not a Mooney p/n. If they gave an oem p/n, you can frequently track it down on the Internet. That said, Mooney was not always precise with those oem part numbers, so some interpretation may be in order. A search for F34-14 yields an ebay advert which appears to identify a cross-reference part number (possibly a different oem), and sometimes those numbers can lead to further searches. The ebay advert calls it a "flap rod end bearing". Something like a rod end bearing may have been used in several places in a Mooney (or any other airplane) so don't get hung up on the suggested use -- it's the part number we are trying to match.
In the end, sometimes you order what appears to be the right part but, when you get it, you find that it does not match the part on your airplane, and you start over.
Finally, I didn't spend very much time on these searches, so you will need to verify these links for yourself.
