How to index oil inlet on k14

[shinobi]

Hi guys
I am putting my 1.6TD back together to go into my syncro vanagon.
How do I rotate the the oil inlet to the turbo? I would like it to be located at the top.
I have removed the bolts and torque spreaders but the center piece with the oil inlet and outlet wo't budge.  any suggestions, ideas or comments welcome.
Thanks
Mark

While I have everything apart I wa going to have an oil retun line madeup from hydraulic hose and fittings, trying to maintian a downward slope.
I'll post pics when its ready.
