I am going through my rally gauge set in my 74 cuda and realized that the oil gauge is no good. Originally the needle could bearly be seen with the lenses on it was pointed towards the bottom. I took the gauge out and the needle feel off. Is there a way to rebuild them or someone here in Florida that would rebuild them? Or is it better to pay 80.00 to replace the gauge. The outside of the gauge looks fine. Anyone have any thoughts on this. Thanks
