On my 69 Coronet the speedometer needle bounces like crazy when car is moving 0 -20 mph.
20 - 65 mph the needle is steady an accurate. Above 65 mph the needle starts bouncing again. I inspected the drive gear. Looked good. I had an instrumentation shop in Virginia check the speedometer head. They said it tested ok on the bench. The only thing left is the cable. Difficult to believe there is something wrong with the cable when the speedometer works perfectly when cruising 20 - 65 mph. Am I overlooking something?
