Defroster vent hoses was the hardest part of my system hookup. It is hard to get non-double jointed hands and fingers up in there. I had the right one come off after the install and had to remove the glove box to get at it. Even then it was an adventure lying on my back in the right footwell with the seat out trying to get the hoses back on the defroster vent by the windshield. FYI, I used the original vent hoses and once they were in place I haven't had to touch them since. I had installed a Hot Rod Air system very much like the one you are working with. Unfortunately they went out of business.

Cheers, Mike

I am at an advantage having the car disassembled! Makes things a bit easier. Even then, I installed and removed the Evap unit 50 times yesterday! ugh.

So, on to the centre vent stack. 

I picked up some supplies. A section of eaves trough foam, some acrylic plastic sheet, a plumbing pipe reducer and one foam gasket.

First thing was to remove the transfer section in the dash. Then I cut out the side diffuser panels and trimmed off the side vent outlet tubes. 

The foam eaves trough material was the perfect shape to fill the void and great non-turbulent air flow.

Then I trimmed the acrylic sheet to fit and opened a hole for the plumbing adapter to connect to the 2” vent hose. 

I then trimmed front and back with foam gasket and then bolted the acrylic sheet onto the transfer panel. Looks pretty good!
