I don't have an answer to your question, but I wanted to comment that I find this to be contrary to my opinion. I much prefer the leather wrapped shift knob in my 2014 than the plastic hard feel of the new knobs, which I've had to use quite a bit between loaners and rentals. Let us know how it goes. I haven't seen that mod done before in this forum so if you do it, you can be the first to share the results.
