Lower gear brace and NACA vents
Lower gear brace and air vents

Here is the left vent completed.

I used Marine grade Goop for the adhesive to bond the vents to the fuselage. I used Goop for the static ports and it works very well.

I painted the vent assembly black to match the actual vent. Plus these are up out of the way and will blend nicely with the interior.

I ordered the aluminum vents from Van's. This set up is fairly easy, just make sure you get the vent aligned properly.

Here is the left lower gear brace installed.
