The original handle is only plugged. After a long time the plastic part in the knob for fixing is refracted at the bar. Plastic is the timekeeping brittle. The RGA has moved into when pulling up in this knob, thus sits very slightly lower. Actually a crazy construction - but that's another topic ...
The new knob is located now almost at the upper end of the rod is fixed with the Allen screws, halved the plugged rubber version in length. The bottom cover of the countersunk allen screws (in the image of the silver ring on the w2c is) unfortunately had to be left, because otherwise the RGA can not unlock path. If the RGA is not pulled up so you can see the threads and the spring of RGA - not just pretty, but it works.
I do not blame the the part, after all, I could have made me wiser before I ordered it. If you do not want so that, as I have installed it, you should therefore look at his vehicle with RGA accurate.
