Last year I started noticing my '68 speedometer needle jumping around ever so slightly. I didn't really bother with it because I had other things to work on. So today on my way back from a long drive, I heard this kind of a ticking sound as I was slowing to a stop. It's hard to explain the sound, kind of a soft clicking type of sound that just happened to be in sync with the slight bouncing of the speedo needle. Do I just purchase a new speedo cable, or is the speedometer itself starting to fail? I'm asking because I don't want to spend the money on a cable if I don't need to. I am hoping that one of you have been down this road before and could offer some help. I don't believe that I have replaced the original speedo cable yet and the vehicle has about 71,800 miles on her now.
