A lot of time just thinking and tinkering with this throughout the week. Finally started cutting some metal. There are two options for the condenser connections - inside the tunnel or outside. Inside is a little tight adjacent to the elevator pushrod and the rudder cables. But outside, I'd need to make some new access panels below the rear seats to access the connections. The 3D model shows inside the tunnel, so I'm going with that.

The hoses have to penetrate the rear seat bulkhead and it is very tight with the existing holes for elevator pushrod and rudder cables. I strategically located the two new holes to provide maximum edge distance between the holes. Still, it felt like I was not leaving a lot of material in the bulkhead so I opted to fabricate a little doubler out of 0.040” scrap aluminum. Then to secure the hoses inside the tunnel in the baggage area, I fabricated a clip angle for the #10 hose. I was able to use a Vans clip for the #8. Then wanted to secure the rudder cables a little more out of the way just in case they ever go slack, so cut a slot in the vans clips and a slot in a snap bushing to slide over the cables. Drilled and cleco'd all of those angles in place to see how the fit looks. Not bad.

Redrilled all the belly scoop holes. And then drilled all of the holes for nut plates. Need to order more single lug nut plates to finish those off.

Mounted the condenser back in the scoop and marked where the hoses will penetrate the bottom skin. Drilled those holes and fabricated a doubler for those penetrations. The AC kit came with two small individual doublers. I put a larger single piece doubler across both holes.

With the hose routing and the condenser hose connection locations, I need something like a 75 degree bend in the connector, not the 90 supplied. I tried a 45 bend connector for giggles but it is not right. Something in between is what I need. Don't know if I can bend the connectors that were supplied.
