I did that few times it is not scary and easy job.
Taking of the needles you have to use playing card to put on the dial/face under the needle then take flat screw driver put it between needle and turn it needle will pop off.

NOTE putting back all needles you have to put them lower than zero because when you connect speedo back to car and turn ignition on they will slightly go up and stay like that.
