I've tried looking around but have had no luck.

Does anyone know the size dzus fastener the rear louvers use? Currently, I have a bolt with a clip shoved in the mounting hardware that keeps the louvers on, but I would like to ditch those for the dzus fasteners so I can clean my rear window easier. The mounting harwdware is ready for the dzus fasteners, I just don't know which ones to get.

If anyone has a link to the right ones, that would be awesome. Otherwise, if someone knows where I might buy some locally (in Arizona), that would be cool too. I would hate to buy some online to find out that they are too long or the "thread size" isn't correct since they are quite expensive.
