I have a "J" type O/D fitted after the MT75 box. It's U/Jd directly onto the MT 75 output flange, stops it shakin' about. It has a short shaft attached to the output flange which sits in the centre bearing carrier.
Works well, gives 29mph per 1000 rpm. Will easily pull 3000rpm if I dared try. Bosch TDi motor. 4.1 diff......
I guess this guy has a 4 speed + overdrive box. Same principal should work, depending on the output shaft from the "front" O/D. Wire in the O/D defeat switch to both to save trying to reverse in O/D, it don't like it. Take speedo drive from the second unit.
