Attached are a few pics of my vent and adapter. The first shows the pieces, the second assembled and the third test fit in the truck while I was working on the sheet metal replacement. I had to make the adapter in 2 pieces because of the hinge design on the vent. The vent is from a Volvo 240. I chose this one because it operates with a handle, not a cable and it is small enough to fit within the footprint of the fresh air heater block off panel. I chose to make an adapter instead of cutting up an original block off plate. If some future owner hates it, they can replace the vent with the original block off plate. It was a first attempt that I stuck with, even with the warts. Hopefully there is something here that spurs a thought for you all and helps.
