I have a 1990 gt with manual 5 speed tranny without cruise control. My speedometer cable is no good and I need to know How many teeth my speedometer GEAR has and if its left or right hand driven. I threw out the old cable with the gear thinking autozone would have the complete speedo with gear. The old gear was white and my rear gear ratio is 3:73. Im driving around without knowing how fast im going so i need your input please
