Birth of the Blue Missile

I saw the post and personally I would put the smaller flange next to the scoop. In the mean time what is headed my way is a four part set. The exterior part is plastic but I really like the scale of the louvers, theyre beefy and I think that is what makes them look mean. The other half are the "drip trays w/ vent tubes. Which to are as valuable as the louvers themselves. I also have the possibility of either using the ones shown here which are 20ga steel or possibly finding someone to make me duplicates of the plastic pieces in steel.
