I bought a #8 fitting and #10 male fitting and dropped off the factory manifold at ArcPro (local welding school) to have the owner/master welder TIG them together for me. Plan on taking a welding class from them this winter when they slow down and when it's not so HOT.
Since the center console is a stand alone art project that will come later and houses two diffusers and AC controls, I temporarily mounted the AC controls and one diffuser under the dash. I temporarily mounted the two other diffusers where the kick plates goes. Got all the ductwork installed and stuffed the AHU back up under the dash. Pretty snug but nothing interferes with the wider linkage.
Mounted the condenser using the brackets that came with the unit. To avoid cutting the core support for tubing clearance, I mounted the condenser out in front of the core support. This leaves about 2.5" between radiator and condenser and about 0.25" from the front of the pusher condenser fans to the back of the grille. Fortunately, I was able to bolt the new brackets to 4 existing factory nuts that are welded to the core support.
Epoxied and screwed the two condensing fans together and will make mounting brackets tomorrow.
