Help Anyone : My 86 Red Coupe Odometer, with 62k just stopped working, or recording miles. The cluster & all the components work perfectly, tach.,speedo, oil,temp,etc. Has anyone had this problem in the past, & know how they got it fixed properly. Can I buy a new tumbler, or is it hooked to the board electronically. I know I can get at it if I take the dash pad off, but what good would that do me, until I have a remedy ? Please jump in with info & ideas, Thanks.
