very very care fully pull them off, i have done it a few times,if you grab it in the middle they do come off,
and then they press on when your done,
make sure you have it lined up where you want it,so you dont have to remove it,
and also i my self have broken the speedo needle,and glued it, which made it heavy, and had to have the speedo recalibrated,so dont break them as there not reproduced, atleast to my knowledge
