Flare outlet on Oil Return for t-25? Need advice- Where to get an adapter

I can't find anything on this. I'm sure it's out there- I guess I can't frame a good search.

Background. I just picked up a new/old stock t-25 Garrett. Model 466546-4. From what I can find it is an obsolete model TB2504 which was standard equip on mid 1980's Nissan Skyline Diesels.

The vendor told me that the unit did not come with any fittings- Including the hardware used to allow the connection of a oil drain hose. I figured I could source it without a problem.

Here's the twist. I get the thing out of the box and instead of the usual drain hole in the middle of a flat boss- to which a plate would normally bolt. I have what appears to be a threaded hole, 21mm in diameter, I think it has 1.5 metric threads and it appears to be for a flared nut/tube.

Does anyone know where I can purchase the flare nut? Or, is there such a thing as a Metric Flare adapter to -10 AN ?

Stumped.....

THAT is what I thought I needed...LOL. I have a threaded hole- not a boss to which I could bolt the flange on this ebay par...

Thanks for looking though - I appreciate it.
