Can anyone help me by advising how I can remove the gear change hub off the column. I want to grind where the original gear lever fits onto the column off and bog and paint in relation to now having a floor change. It appears that the wiring will stop the hub coming off is this correct.I also purchased a new hump for CRS and the gaps under when you just put in position to see what the fit is like is a bit big. Do you have to cut and just fit as you go or should it lay flat and have very little gap before you start. HELP.
