I installed overlay gauges on my mustang today. I had to remove the needles in order to put the new gauges on. After I put the new gauges on, I put the speedometer as well as all of the other needles back in the correct position. After I out the dash back into the car, the speedometer needle had moved up to 25, so now my speedometer is off 25 mph. How can I fix this and make my speedometer start back at 0 ?
