If you want to wrap the individual piece you will need to remove the entire combination meter. IIRC, there are a couple of screws holding it place before popping it off. To get to the screws, you need to remove the back cover.
Disassembly is pretty easy especially with the work that you are doing. I'm estimating 10 min. tops to get the cover off.
Reference my thread for some pictures. I had to cut it down due to space constraints.
