Diagnosis? Prognosis? Treatment? My 77 Chevy truck speedometer going crazy. Works ok up to 40 or so, then starts acting crazy. The faster you go, the crazier it gets.
The cable may be binding up in the cable housing. When it reaches a point with enough twist/tension, it slips free and shows a jump in the speedo reading. Try lubing the cable inside, check for any place the housing is kinked or in a bind.

Ok, I'll start with that. It sounds affordable.

Craigslist is a bad place to try and get advice.
