If you have the means, I created a dial plate using sticker printing paper and an internet photo for reference. Not perfect, but pratical until i had to send camera in for other repairs and had it replaced. Just need to make sure to match the camera ...
Were you able to get a plate and reattach? I have the same issue and concerned with how to replace the entire dial, or just take the plate off new dial and attach to dial on camera. Seems like nobody at Canon customer service has an answer and tansfe...
