Okay, so when I backdated my car about 9 years ago:

During that project I removed all of the AC components as most of them had failed. Since then I kludged together a fresh air blower system and that worked "okay". Now I am ready to start a new project and a newer AC system is it. I sold some of the old parts and that was a bit of a mistake. I had to buy a used EVAP box recently and that was way more than I sold mine for. Oh well!
The first bit of help I need (more to follow I am sure) is that I don't see in the PET how the outlet for the evaporator blower (the large round duct on top) connects to the bulkhead. I see images of a duct piece, but I don't recall what that flex duct joins to. Anyone know what I should be looking for in my hangar full of parts? Thanks in advance!
