Hi Teahead, thanks for asking.
Is a one-off i made for myself , it does not reflect the work gotten into at all, i just wanted a good home for it , and beware it for the skip..
All the work can be done from inside the car.
You have to take off the knob and rubber first , then remove the two m6 nuts , install the first ring onto the 2 m6 studs , and after that install the upper part with the two m6 bolts.
reinstall the rubber and knob and the job is done. it really is selfexplaining..
regards mark
