Best to know the gauges work before installing the screen decals. The 2 thermalt gauges should read 20 ohms or 13 ohms across their posts and you just might have one of each ( I forget all the places where 13 ohm fuel gauges are ). Your amp gauge looks centered so that's a good sign. I would check the magnet for cling ons anyway and clear with compressed air.
Then repaint needles if you wish. Masking with aluminum foil is easier than removing the needles although you'll likely remove the speedo needle to install that decal. Look for instructions before pulling on that needle since some of them have a dab of epoxy to counter balance that can pop right off if the needle is bent there. Anyway...
Correct water base acrylic needle paint can be found at ebay. Tiny bottle @ approx' 7 bucks contains a lot more paint than you'll ever need.
