The aluminum gear knob was delivered promptly, but just as quick to put a confusion in the assembly. The description for reverse gear shift lever with locking is in fact formulated fundamentally wrong, so I have been trying to send the item back. Based on my technical ability but I succeeded then but quite quickly. Looks good, sits and sits comfortably in the hand. Installation tip. Rubber adapter together with threaded ring of the knob onto the thread of the shift lever to Lathe threaded end. Then cut off the protruding rubber, threaded with long hex - fix screws, finally screw the shift knob firmly onto the lower ring. Done.
