NOS replacement panels used to show up on eBay all the time, however none that I noticed today when searching for one. Also, there used to be a SS member that made a vinyl overlay with the original control panel markings that you adhered to the "instrument panel" that was reported to have worked quite well.
You should post what you need in the SS "parts wanted" section. I'm sure someone has one collecting dust in their shop/garage that they may be willing to part with.
There were panels on Ebay for quite a while. I purchased 4 of them about a year ago, but the add is now gone.
I sent the seller a message to see if he is sold out, and will let you know if he responds. When I bought mine he had quite a few available.
Several years ago there was an SS member selling sticker overlays for the wiring schematic and I think the control panel as well.
If all else fails, you can make labels with a Dymo label maker. It uses colored plastic tape. I re-lettered a panel 5-6 years ago this way and it is still in use. Use some good degreaser on the panel before installing the tape. This is not the best way to re-letter a panel but if serves the purpose.
