Hey guys.
Google Roverdrive and you will see and can read all about them. I ordered one for my Series III with 202 Holden motor. I have attached pictures of a Roverdrive and a Fairy overdrive. Have owned a Land Rover with Fairy OD and it was good I'm guessing that my Roverdrive unit will be even better. Fairy OD can only be used in 3rd & 4th Hi box Roverdrive you can use in all gears forward and reverse according to the factory. I hope this helps Fairy OD can be purchased from Rovers down south an American company they make them brand new. They also have service manuals and parts.
