Ron, as with most other Triumphs, the OD is an add on unit. YOu must get the
Unit, the adapter plate, the longer transmission main shaft made for the
overdrive and the applicable wiring parts to actuate it.
It is probable that the drive shaft will also have to be modified (probably
shortened) to accommodate the new length of the transmission.
