Hi an update for anyone whose interested, got my box out and put the two boxes side by side, it looks like the only difference after removing the gear stick assemblies is the length of the selector shaft and the handbrake actuator now all I have to do is decide if its worth striping my old box and swap the shafts or some how lengthen the disco selector rod and change the hand brake, the bell housing drive flanges and first motion shaft are all the same. Ill let you know what I do about the selector shaft.
