Got the rain hood/duct for the A/C box assembled this weekend. And yes...it was a pain to put together. Still needs paint but that can wait until much later. Have it screwed in place but ran out of light for pix of the final test install...only the earlier-in-the-day version.
The final version with the "stabilizer" down the middle added.
Test fit before adding the rod in the middle or screws. The roof deck will align with this unit and be full width & length.
From the other side. Now have the center stabilizing rod welded onto the fins and it is drilled and screwed to the A/C box. Will be adding a stainless steel mesh filter behind the fins to keep birds & mud-daubers out. Same kind that go into range hoods. Pretty happy with the way it looks. Like I said earlier, the design was taken from a 1930's rear engined transit bus which had a big "breather" at the back of the roof to vent the motor heat. Always liked the streamlined, Art Deco, industrial look of it. Hmmm...gotta' wonder what it would look like chromed?
Next comes a couple of small window deletes that need some work to fit.
