I think you will also find that the top bar runs into the heater unit/box behind the dash, so you need to think about possibly losing that. I removed the whole lump completely.
You will also need to do some cutting and welding onto the levers on the gearbox...
As for the reverse cable, i shall just be running something along the lines of a bicycle brake lever on the gearstick once i go back to using a 6 speed box when it arrives..
