Looking good. Thanks for posting pics of your progress. Im working through the same install at the moment, so seeing your progress is keeping me motived to keep pushing forward. I used that same vent setup that you did, but I cut it between the two rectangular vents and extended it to make room for the controls. Ill take a pic once I get it installed. I found with that vent that if I placed the round passenger side vent where I wanted it, it put the two rect. vents too far to the passenger side for the driver to get much air.

You would have had to modify your glove box no matter where you placed the evaporator. I did mine based on the mockup unit, and thought it was good, but now that the final unit is in, along with all the vent hoses, looks like I will have to modify it even more. So, I would suggest not finalizing anything on the glove box until everything else is in. Ill be interested to see how yours turns out!

Yes, please post some pics of your glove box fix, and how you cut the vents and where you mounted the control panel.

Was able to finish up the A/C lines today and evacuate the system. Looks like it's holding will check it again in the morning.

I had a friend that can do all on cars. He went over the wiring diagram with me and I took some notes, and I think I can finish the wiring this week. Also ran the ac duct work, no way I will have a glove box.

Also working on routing the heater hoses and heater control valve. I'll get it figured out eventually. The heater hose near the air cleaner with the yellow tape, is the one I'am trying to figure out.

If the unit is mounted against the kick panel it clears the glove box, which creates a problem with running the lines thru the firewall,Image

Not a unsolvable problem just another challenge

Heater hoses are done, the one on the back of the intake runs from the back to the front. Used a 90 fitting and it runs across the top of the a/c compressor to the passenger fender with the rest of the a/c and heater hoses.

My son doesn't like the fact that the hose runs in between the two a/c lines. I,am good with it for now.

We finished up the plates for the heater hoses and found a place to mount the heater control valve. It's kind of hidden and away from the headers. I think it worked out pretty good.

I think it's coming out pretty clean for my first Vintage Air install. I'am going to do a little bit of rerouting of the wires on the left fender well later this week.

I needed a keyed ignition source for a trigger wire for the compressor switch. I hate to shove a spade connector in on one of the old style glass fuses. So I found a lug on the fuse panel that I think maybe was used for the factory a/c system. Was able to push a spade connector onto the un-fused lug with this fuse set up. I think it's going to work well.

I will try and post a pic of where I plugged it into the fuse panel once I'am done.

Thanks Ed for all your help! Yeah, my goal with this thread was to help others that were thinking about doing A similar a/c swap. Even if it is, Wow, I would never do my rig like this. They can hopefully take some of the ideas or Technics I used, and get their Wagon some ice cold air!!!!
