Fairey o/drive linkages for stage 1

[LJH]

I have bought an used fairey overdrive for my stage 1 series III. It has come with linkages for a Range Rover which are not suitable for the Series III. Any information about the linkage design for the stage 1 if it exists would be greatly appreciated. I do not want to get rid of the centre seat.
