I noticed that my back window screen(the long one) was very loose and flopping around. After checking it, there are screen clips that hold it in place. I noticed that 3 of these clips were gone, so I searched the internet for them.
Here is where to get them if you meed them.

They are $1.20 a piece, which is a rip, but its the only place I could find them.
