the easiest part of doing this was the clutch. remove the chevy 9 inch clutch, pull out chevy pilot bearing and machine it to fit rover input shaft, install on to the chevy flywheel the rover 9.5..or 9.25 what ever size it is clutch..........and the bolt holes line up!!!!!! .............i dont have my exhaust on yet but yes i have driven this down the road.......( yes under its own power) and yes i have even shifted all 4 gears..........this works. here are pics of the engine.
