Source to replace a damaged tube cage on a Muzishare R100 300B to 845 integrated?

Hello Fellow Audiophiles!

I recently sold a lovely Muzishare R100 300B to 845 amplifier to gentleman in California. The amp was shipped via Fed Ex in original packaging BUT somehow the tube cage was damaged along the way.

I am hoping to find a replacement tube cage. Does anyone have a resource, or (for those of you without pets or young children!) a cage they are willing to sell?
