Some quick phone pictures, real camera is already packed away for the move.
Test fitting sideways

Blurry photo with wiring rigged up

My worst bend, puckers a bit near the top on the inside, the rest of my bends didn't do that and this was the very last one I did

Sitting on top of it's home

The top with the 90's that ended up being a touch too tall to fit through the existing opening.

They join into one to travel to the res.

full length. It's can be hard to tell in the photo but they drop down into the T fitting which is lower. And the next run actually moves down and over to the compound rotary.

Side shot, only soft tubing I used. I test fit a hardline in there but I simply could not get my fingers in there to do anything with it. So going with soft tubing gives me the slack to dismount the assembly off the tray then disconnect the tubing.

The in-ports come in from the bottom port on the tray through the soft line to a direct threaded T fitting and hardline over to the other radiator. They are plumbed in parallel.

Edit: Overall working with hardline has been fun, but it sure is more time consuming.
The case is also tapped/died? so the tray will actually be secured in part by thumb screws.
