AN oil fittings for the bottom corners on the Passenger of the block?

Does anyone know where to find these and for a single turbo do you need to split off the oil out let to run to both?

Thanks

Most single kits drain to one of the oil inlets down there and block off the other one. I am not aware of any that use an AN fitting on the block side, but perhaps there are some. Mine just connects to the 2-bolt flanged connection in front.

I just use the front oil return with a -10 an. Have a blockoff plate drilled and tapped for a fitting adaptor from npt to an.

This is a good question, Which oil drain would be better, front or rear? I would guess the rear would be better to aid drain the turbo while accelerating but the front has a larger internal diameter.
I'm going to finish my exh manifold and the DP then see if there is any room left to run a line back there otherwise I'll have to use the front. I machined out a flange with a -8 orb port and also a o-ring to use if I do use the rear drain. If I can't use the rear drain I'll just bolt the flange on a put a plug in it instead of a fitting.

Here is a pic of the flange. It's the one in the middle, the one on the right is for the turbo drain.

Thanks for the complements guys. I'd make more but they are too damn time consuming with the tools I have. I'm using a old bridgeport mill that is WAY out of tolerance and a bandsaw that is missing more teeth than it has. It took me ~2.5hrs to make the turbo flange and ~3hrs to make the rear plate block off/turbo drain flange.

Here is the other side. The way I figured, why use gaskets when you can use o-rings
