does anyone know of anyway to correct the gauges? i took out the needle on the gauges as i was replacing them with white face gauges. after everything was back, i took it for a drive. i drove past one of those police speed checks on the side of the road and found that i was goin' 33, but the speedo was reading 25. i'm not sure if the other gauges are correct now. the temp looks normal, but not sure of the rest. thanks.
