Well I mean on painting the top case as well, but I'd also like to replace the plate so I can easily replace the switches.
If you mean that you want to be able to open the switches and change out stems and springs, then you are looking for a
universal TKL plate.
The group buy in that link is the last one I know about, and it is over. You should probably check the classifieds and post there when you meet the requirements to post in classifieds.
Good luck finding what you need.
