Hi I am hoping someone can tell me if gauge overlays can be safely installed by slipping them over the exsisting needles on the exsisting gauges-without damaging the needles or changing the accuracy of their readings (if I am gentle installing them of course)?

Also what secures the overlays to the top of the exsisting gauges when installing them? Thank you for any information and help.


By the way it's on a 91 civic hatch dx manual w/o tach.
