Model 4 cockpit air vent help

[climbak]

Hey guys, I recently picked up a Skystar Classic IV and it has the cockpit vents on either side under the panel. They are opened and closed with a little threaded wheel that a plastic stud runs through and those studs are glued to the vent panel. One of the studs broke the other day and I can't for the life of me figure out what it would even be called or where to find a replacement. I tried calling Kitfox, but they didn't know. Here's a photo of it in case someone recognizes it.

Anybody have any idea where to get a new one? 26240

I didn't know what the vents were called, but they are naca vents. They don't seem to have this specific one on aircraft spruce, but I'll keep looking. Here are a few more photos.262482624726246
