OK. Tore it apart again. I'm adding the AC in. As it turns out: "I'll just add it in later" wasn't such a good idea.
And then, of course, you get the five most expensive words ever spoken: "While you're in there." (four words, I guess, with a contraction).
So, here's the list of stuff we're trying to do.
Ditch the Evans. Didn't like it. Going to water and water-wetter.
Create and install a duct from the bumper to the radiator.
Install the AC.
Install the AC includes several sub-items - because before you can do anything, you have to do something else first.
Sub-item 1: Seal up all those holes in the "firewall" including making a backing plate for the extremely cool Rennline smugglers box cover with all the holes in it.
Sub-item 2: Move the AC system box so that the hose connections will fit in front of the gas tank.
Sub-item 3: Install the switch block in the center console (done)
Sub-item 4: Run more giant lines all the way up and down the bottom side of the car.
Also, in order to swap out the coolant for water, I'll need a coolant reservoir.
Here's the progress pics. That damn vent took 3 weekends. It's finally done except for the final welding.
