I'm certain you cannot order those. They were made only for the EX500.. about 30 years ago.
You will need to either find replacements from a parted out unit or try to find someone with a 3D Printer that can copy the originals.. then you'd have to label them yourself using a standard printer to get the numbers back on them.
good luck..
