knob

The arthritis in my hands is having a positive result.
Gripping the steering wheel has been solved by a pair of "Dents" driving gloves.
Vibration in my short shifter has been dampened by my new knob, a billiard ball, it fits my poor grip better as well.
The unkind among you may be smirking but you won't see a bigger knob in Cornwall.
I have quite a few balls left, yellow, red, one white and the prized 8 ball, sized to fit your particular shaft.

Here is the proof
