Has the speedometer or the odometer stopped working in your TC? 
 
If so, you can send it in to us here at RDI and we can repair it for you.  Price is for our repair and return service.  We also take the time to properly calibrate your speedometer while it's here so you will have not only a good working unit when you get it back, but your speed will be accurate as well.
 
You can send us just the speedo head or the entire cluster.  Whichever you prefer.   If there are other things not working on your instrument cluster please be sure to place a note in the box so we can repair that as well while we have it so we can save you on shipping it back and forth multiple times.
