I've been working on the evaporator box and i found a crack where the box mounts to the firewall. The square hole is where the air from the blower comes in. The hole had a crack on the top left corner. I took some Lexan and some epoxy and braced the area around the hole. It is at least twice as thick now and i cut the access plastic of and cleaned it up real good.

The gasket where the box mounts to the fire wall is the same one on the heater duct on the non A/C trucks. It is a little small so I made a template on photoshop. I've ordered some 3/16 and 5/16 thick ultra soft open cell foam from McMaster Carr for this build. The top of the evaporator box has a thin foam like 1/16 thick glued to the underside of the cover. haven't found a suitable replacement for that yet.
