As above fit the assembely in the car and posistion whee you feel comfortable then the cables come with a rubber guide/gromit which needs to go through tunnel/floor area.

No trimming is needed just route so there are no tight bends etc.

Simply clip on the box and you have 6 gears which feel very posisitive.

The next mission is the driveshafts ive got the shafts made now i just need to solve the rear halfshaft bearing mount.
