So, my odometer quit...

[jb1016]

...And I'm trying to figure out if it's worth the trouble to fix it. I've got a '93 with the original tach cluster, and it seems like every thread I can find on the internet talks about either an earlier or later style. The trip meter hasn't worked in the nine years I've had the truck, but the odometer just quit.

-Has anybody out there made theirs operable again?
-Can it be fixed - does anybody sell the little plastic gears, or can you scavenge them off a junkyard cluster? I'm just guessing that broken gears are the problem at this point, since I haven't taken it apart yet.
-Or does the whole cluster have to be replaced? And if so, is it possible to wind the odometer back/forward to my mileage?

Thanks in advance to anybody who can point me in the right direction.
