Dont know why but at 136999, the odometer and trip odometer stopped, but the speedo still works. Is there something in there that commonly goes out, or something that could've gotten stuck? I did try resetting the trip odometer, but that didnt do anything.
yup. There is plastic gears inside the odometer that melt together after awhile, happens to EVERY odometer in the fox/mn12 series. so you have 2 options, new odometer, or new gears for the odometer(better quality) here is a link to the gears. http://supercoupeperformance.com/partBrowser.aspx?partId=493
Nice dentside- i have a 79 of my own- what mods do you have in it?
I know mine stopped for a good 25,000 kms, I freed mine up by pushing the tripmeter reset in really fast while I was moving at a decent speed. Dont know if that will work for you though, but did for me :)
