I just sent my spedo back for repair for the second time (Didn't fix it the first time) and it has scratches on the screw that holds the face on. Am I just being overly cautious or would you send it back for another try. I am worried that in the future someone could see that the guage was opened and think I had the milage set back. I actualy had them set it ahead so the time it was driven with a broken Odometer would be acounted for. I enclosed a picture to help (though its not very good)
