if you have an oreillys close by they have a supplier called disco. they carry many of these in bulk, but not in stock. possibly a few days to get. I will try to remember to get the actual part number when at the shop.
there are a few different part numbers that look identical though. they are often different colors and that does not mean they will be the same as the original colors were. they look the same but will fit slightly different hole sizes. one caution is to not get ones too tight as the part you are putting back is plastic also. you need it to hold firm but just so. don't be afraid to waste one testing it in the hole and pulling it to check before installing the panel with new fasteners.
