The last major component of the system is the evaporator. I bought a universal under dash unit off eBay. Here are a couple of pictures of it mounted:
In case someone tries to duplicate my setup, there was a major problem with the evaporator unit as delivered. It moved very little air through the core. Upon inspection, I noticed that the blower motor was rotating the wrong direction! Since it's a DC motor, that's a simple fix. Just swap the positive and negative leads going to the bower motor. That made things much,much better but I made one more "improvement". I swapped the blower motor fan blades side for side. This result is that it reversed the slope of the blades. A squirrel cage fan will move a higher volume of air with reverse pitched blades than with forward pitched blades.
