restoring speedometers or parts???

[HONDA_ATC_FREAK]

I recently bought a atc speedometer and it has been in a wreck or two by the looks of it but it works. The outside housing is whats in bad shape it has two big dents ironicly the glass and the inside is in great shape, must have been garaged. It does work though and it will make a good rider. I would like to get parts for it like the outside housing and the face ring. I was wondering if anyone restores them or knows someone who does. Or maybe has a junk one that I can use for parts.
