1867 Barracuda Speedometer Problems

OK, so my Cuda's spedo isn't working. I looked under the dash and the cable was just undone. When I screwed it into the dash and started the car, it started jumping up and down and making noises (the speedometer, not the car :toothy10:)...

Where can I get the spedo fixed? (If that is the problem).

EDIT: DAMN IT! HAHA. WRONG DATE.
