well i took my dash apart to try to change my blown dashlights, only to find they are not serviceable, when i put the dash back in the speedo needle and rpm needle fell out of place, i put them back in at 0 but when i re installed it and drove the truck the speedo fell down below the 0 and the rpm was 1k at idle, does anyone know a way of re calibrating it?
