Teaspoons either side of the needles does work, the trick is to get them back on in the correct place though. I had alot of hassle before..
If you have to take needles off my advice would be to take photos of where they are before taking them off (with ignition off).(ignition on) Also take a photo of your fuel gauge, your temp gauge (when at normal running temp) and what revs the engine is doing at a certain speed and check what that speed is on a sat nav. This way you can make sure you get the speedo right first with the sat nav, match the revs to the speedo etc. Good luck!
