NACA Duct help

[JeremyC]

I am just getting started on some minor repairs to my recently purchased II LTS. The canopy skirt has NACA openings, however the vents are long gone, do any of you all have some recommendations on replacements?

Does AS sell them? If not, shouldn't be too difficult to make your own. It would make a nice beginner project if you haven't worked with fiberglass before.

They sell what looks to be a shell with no opening or a means to keep it closed if you cut the backside out.

I made mine from fiberglass with the exhaust end wide open. In the summer, I’d leave them open, and in the winter I’d plug them with a foam plug. I still have the mould.
