>>>My speedometer will not go back to
zero after advancing past 20. When using a drill to test it will not advance
past 60mph and advances with jerking motion. Not the original as I replaced
the original. Purchased the car new in England in 1961 while stationed near
Coventry. Is there a way to tell if the speedometer is compatible with
overdrive? Is repair a DIY?
>>>Thanks much.
