I have a 69 Nova and need to fix the speedometer, fuel gauge, and the selector indicator that shows you if your in reverse or what gear you are in. So first the speedometer is bouncing back and forth and is off by quite a bit. Is this just a small gear driven cable that might be messing up or what would cause this? Next is the fuel gauge, it is constanly bouncing back and forth also. Does this use just a float in the gas tank or what would cause this? Lastly the gear indicator doesnt move at all. Is there linkages in there that maybe need to be reconnected or do I lose that since there is a aftermarket 350 and t-350 tranny in it? Sorry for all of the questions but im really anxious to get started on this project.
