Update

After messing about with different length rods, i found making it longer made it slightly better but was still having issues coming down the gears ect and in general gear selection was fucking shite.

Removed box and it selected fine off the car

Bought a concentric hydraulic bearing setup from Brands hatch performance and fitted that, gear selection is now perfect.

Raging with the amount of time spent pissing about trying to make the external slave setup work
