I replaced the gauge cluster in my 67 Dart GT. It included a new speedometer cable. Everything is working beautifully (gauges etc) except the speedometer and odometer. The needle will occaisionally move to an area and stick there for a time. I have unfastened and reconnected at both ends of the cable housing with no result.
Any ideas/suggestions?
 
There is a magnet in there.

If any rust scale or metal has stuck to the magnetic pick up it can hang up.

Whenever I mess with a speedo cable on these cars I take it as a given that I will have to jack up the back wheels, run the car in gear and mess with the cable angle into the speedo head until I get it where they run smooth.

At the transmission or speedometer end? The gauge cluster is new, aftermarket. Now that you mention it, when I removed the cable from that end, there was something stuck to the cable end.
 
I have no experience with aftermarket speedometers, but the originals used a magnetic pick up.
 
Just to clarify... The gauge cluster is new or used. There was a post here in the last two years where a member took his cluster apart and when he put it back together, he got the needle on the wrong side of the black bar at the top. It would work to a few miles per hour then stop. When he slowed it would start working again.

it's new, aftermarket.
 
I got so tired of messing with the speedometer cable and pulling cluster out. I customized the cluster used after market gauges and GPS speedometer no more cable.
Speedometer is dead nuts accurate ,haven't found a place that it has gone dead yet. I probably have less then $100. in it .

OK-the speedo is new aftermarket. Does it use the original mechanical speedo cable which plugs into a Mopar transmission? Have you pulled the cable out to see if it's good?
