How did you determine it was the evaporator?

First, I would like to thank you all for the kind words.
After spending almost a year now, on this forum (and the pelican forum), and seeing the kindness of this community, and the wheeling to help each other, it was a no brainer for me.
I learned so much (and still learning) from the forums members, so I’m happy to be able to pay back.
As for your leak issue.
As the evaporator is probably the hardest component in the A/C system to replace, it is the easiest to diagnose.
First you need to charge the A/C system with AC dye. This is a special fluid that glows under black light.
Look here:

AC dye works. Here's how to use it right. - YouTube
You will need these:

Ledwholesalers 400 Nm Uv Ultra Violet Blacklight Flashlight 3 Aaa,7301uv400 - Amazon.com
As you probably know, when you run the A/C, and the car is not moving, you will have a puddle of water under the car. This is the moisture in the air, condensing on the evaporator and accumulating on the bottom of the air box. If the evaporator is leaking, the AC dye you put in the system will mix with the water, and you will have a very nice glowing puddle under your car.
In my case it was so obvious, that I didn’t even needed the black light to see the dye, the water came out greenish.
Looks very cool tough with the flash light and glasses, especially if you are an 80’s fan.
If the leak is not coming from the evaporator, the dye will help you locate where it’s leaking from.
Just follow the lines of the system.
good luck.
