With the battery tray assembly in place you need to wind the outer E 80 nut till it contacts the G50 pate then turn outward another half turn or so, it needs to actually be a very firm outward push on the G 50 plate so when the foot rest stud nuts are fully tightened that the G 50 plate does not distort inward. If this happens it will upset the gearshift, the top of the plate will bend inward even a few thou will upset the shift. Then tighten the inner E80 nut against the outer to lock it.
