B6200/B7200 Etc gauge switch quesitons

[Code54]

Has anyone removed the gauges and switches from the dash of a B7200 or similar machine. Im repainting it and when I went went to pull the dash apart tonight I noticed the switches didn't exactly seem to come out easily. I don't want to put much pressure on them until after I asked if anyone knows how they release? One has a nut to unscrew (that makes sense and is obvious) but the other does not. I also noticed the fuel gauge looks like it may have an outer ring you remove but I am not sure and didn't want to start twisting on it too soon.
Thanks for the help
