Question about stock twin turbo oil feed?

I am trying to find out the thread size of the oil feed galley on the stock FD twin turbos. I have searched but most of the posts were about aftermarket single turbos.

Thanks in advance.

I think it's actually a 2-bolt flange, not 100% sure (been a LONG time since I saw stock twins).

What are you looking to do?

I am putting FD twins on my FC, and I am therefore making custom oil feed and drain lines. I don't have the twins in front of me but I remember the hard line being connected to the turbo via a banjo bolt. I was hoping to put a -4an adapter in there.

The thread on the banjo bolt (oil inlet) is an M10 with about .5" of threaded section. The head is a 12mm.

The oil return lines are 2 bolt flanges held with those screws with 10mm heads. The threads on those are about 20mm long and sized like M6 or something. Whatever size thread all those 10mm bolts have.
