I'm just wondering how to roll back the milage on the gauge cluster? The one I have is messed up do to taking off my indiglo gauges. The gas gauge is messed up, it keeps going down and the back up. I am going to be buying a used guage cluster off Ebay but it has 100,000 miles on it and mine has 95,xxx. Is there any way to roll it back? If so is it hard to do?
