My buddy 3D printed this oval duct that you can stuff in the area above the gauge cluster. I have aftermarket gauges, but this worked great for me. He can print more, I'm sure he still has the CAD models. If people are interested I'll try to get him to jump on here and give everyone a price. It was 2 pieces and I glued it together with JB Weld Plastic weld.

Thanks for the shout out Pat! I'm working on updating the model slightly so you can attached it to the underside of the dash with magnets. Then it will really be a solid solution!

I printed this out of PETG-CF from Atomic Filament in Indiana. Will handle the heat or the cold easily.

Andy,

Came for the a/c thread, now somehow I feel the need to make plans for Oklahoma.

Andy,

Here you go fellas, just what goldduster318 stated above I made this to complete his A/C install for his 1970 Duster. Made from PETG-CF it will handle all the temps inside our A-Bodies interiors. Comes in two pieces and is assembled with JB Plastic weld at the seam.

If you guys want these I can make them for $40 shipped in the lower 48 US states. PayPal is [please no email addresses in open forums, take it to a private conversation]. I have material in stock and ready to go.

Did you make it to the Southern Plains Mopar Fest? In the future I would like to start a little FABO get together there. I missed it this year due to my Cars n Coffee event I run being scheduled on the same day. I'm refining dates for next year so there's no conflict.
I am 30-40 minutes east of OKC, about 6 miles S. of I-40. If you are ever traveling this way hit me up.

Yes sir we were there with our 69 Charger.

A little more progress on our Classic Air install. Now just waiting to get the engine installed so we can finish out our installation. Also, do you guys know how to wire in the Trinary switch?

Yes.

Black or wires are switch for compressor on/off. Blue are for the fan.

Black wires: Below 27psi it will not let the compressor turn on. Above 380psi it will turn the compressor off.
Blue wires: Above 254psi it sends the signal to turn on the electric fan.

This diagram shows wiring pass through signal for compressor clutch, and using the "blue" wires to ground the fan relay switch.

Don't forget to crimp your AC hoses!!! Use a silver sharpy and put a mark on hose and fitting so you can keep same position when doing the crimps.
