Source for engine vent screws? Ive seen Butterfly Wing Screws on the internet and I have no Idea, if they work or what size to get....any sugestions?

The fold-able wing screws for the Fiero air grills in my opinion were a specific design used only by Pontiac. If you want to adapt a standard wing screw the 1/4-20 is a popular size. To use it you'll just need to change a small washer and the slip nut to the 1/4 -20 size. Its not original but it works. If you want a closer copy just just a Dremel and a metal burr bit to shape the ears more like the Fiero screws and paint them black. Once in a while you will find them in the mall but we've had some gouge artists selling them for as much as $25 each, talk about greed!

The thread size should be 1/4-20.

Some people simply use camera mounting screws like these:

You can also just get stainless steel screws that will never rust in that thread size. That way you will have a very clean look.

I've ordered some of these. They can work but the heads are pretty small.
