I made the stupid mistake of taking the speedometer needle off when I replaced my gauge face in my 99 lude. Now, it don't work right anymore.....

The needle don't come down to 0 but to 20 (km/h) and goes up to mutch...I'm rolling around 50 and it points 100 !!!

I don't know what to do......help me please!!!!
