1.75" Spa eyeball nozzle thread? Who makes these?

[wtfbliz]

Bought a house with a pool that has 8 jets with 1.75" wide threaded holes set into concrete.

The nozzles and retaining rings are brittle and do not adjust so I unscrewed them, see pics.

What are these and where could I find them? Everything I see on the internet is 1.5". Literally cannot find 1.75" anything.

Thanks!

Maybe @RDspaguy has ideas.

While not an exact match it looks like the retaining ring on the hydroair eyeballs are 1.75" and may work.

Got an order in will update if it's a match.

So those did not quite fit and are not the appropriate part. The retaining rings are the correct diameter and thread pitch, but are meant to screw into something backwards to mine and only screw in a finite distance.

I am in trouble
