Just an FYI regarding the screens for the Aero tunnels on the NFGT. I recently bought a set and installed them today.
Very well made and a perfect fit. They will do the job they were designed for. I highly recommend them.
One problem... the factory installed screws are too short for installation. The kit should have replacements included.
I purchased M5, black, allen head screws that were the same overall length but were threaded the entire length. I reused the washers. They are metric and available at Fastenal.
