I have a 1967 MGB and the speedometer became erratic this past week, Initially it would fluctuate from 60 to 120 and eventually now swings to the stop at zero. I initially oiled the inside of the cable to no avail and then replaced the speedometer cable and the right angle adapter but again to no avail.
Do you think that I need to have the speedometer serviced? Do you or Rusty Moose Garage service gauges or where I can have it serviced if that is the rectification.
Thanks John for your advice.
