Ok, decided the next step actually was to re-install the OBA. This took longer than i thought, but atleast its done!
So with the York on the passenger side down where the smog pump used to be, i had to completely rebuild my manifold. Started with the bracket to mount it:
after multiple tries, the rough draft:
the oil return for the york crank case is buried down there. I can barely see it, let alone get to it
So i bent up some 1/4" stainless tubing, to get it out and in the open:
Much better! manifold done and installed!
That round black cylinder next to the alt is my intake filter.
3½ gallon tank underneath the rear bench seat:
air chuck at front bumper:
...and the air chuck at the rear bumper:
I still have to re-run the air line for the ARB. Now that the solenoid is on the other side of the engine bay,the supply tube is no longer long enough, so i have to get some more. But aside from that (and the wiring), the OBA is done! So with that done, it looks like i cant put it off any longer, and next week ill be doing a ton of wiring.
