i just got a 93 pickup.
its been in my family forever, the gauges always worked, until a few years ago, the speedometer stopped working, but the gas other things still worked, we went to a junkyard after that happened and got a new gauge thing, and it worked for about a year, but now that i have it, it still doesnt work, any ideas?

 

Is the spedo cable hooked up to the tranny? might be able to take that off and spin it with a drill and see what happens
