My '71's odometer just stopped working. First the main odo and then the trip odometer just a week or so later. I assume the gearing his going (the speedo still works properly) Anyone have a sense of the cost (rebuild and local labor) to getting this work done? I know I could do the disassembly and reinstall myself, but I've got big awkward hands and it is tight back there, and frankly I'm just not into it. I"m assuming when you do this you get a full rebuild (of my original - I don't want a mismatch) even though the speedometer is working fine. Any guidance would be much appreciated!
