Okay, a lot of you peeps who have a visor but cannot find the clips needs to have an idea of what they look like. From there I'm sure someone can easily fab these little gems. They do not appear to be very difficult to make. I'll even give you the dimensions of the clip itself and the hole size so that you can make exact copies.

The posted pic details all of your necessary parts needed along with a AAA battery to give an idea of how long they are. if you put the positive end of the battery into the hole it fits perfectly...just to give an idea as to the diameter your going to look for.

The nuts are made of plastic. I'm going to the hardware store and find a more secure kind of screw so that that my visor doesn't grow legs to find a new home.

the body of the clip not including the bends, measures 3.3 mm
the tapered bend measures .4 mm
the lower bend measures 1.7 mm
the hole diameter measures .7 mm
the width has a diameter of 1.5 mm
