If you have a Borg-Warner T5 transmission with a 9-tooth speedometer drive gear, Stealth Conversions has a 90° angle drive unit with a .66:1 ratio that allows calibrating the speedometer without having to remove the tail housing from the transmission. It is very difficult to change the speedometer drive gear on the T5 transmission. The 9-tooth speedometer drive gear is red. The 7- tooth speedometer drive gear is purple.
