HELLO , I looked&looked all over the net TO try and find a replacement speedo screw in gear that looks all steel to me and it seems to be a 1 piece unit from the factory? Does any one know where i can get any info about replacing it or is there a updated version of the old one in plastic? 2 teeth are missing ,it does spin then stops at the break . AS ALWAYYS THANK YOU FOR ANY HELP YOU could give me . BJF
