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..
