Here is the GM Piece, it looks exactly the same as what I've removed, save for the larger O-Ring.

I have that Russell fitting in there now, but it sticks out and has visible thread. Notice that the pressure regulator only has like 4-5 thread turns, and this part show below has a small amount as well. It's entirely possible the extra threads are meaningless on the Russell bit, and this is much ado about nothing, but if there is part that solves it all, I want to find it. I've thought about just getting a reduced pressure flow adapter, since they make them directly to 6AN, and just seeing how the steering is when it's time.

I'm running the PS cooler because they are cheap at the yard, not terribly bulky, and GM engineers though it was swell. Since I'll be running fluid down to the HB, I bet the lines themselves will help dissipate heat, but assuming that I have no leaks, I see no real downside here. I don't usually pay extra for peace of mind, but when I do, its under $40.
