i checked if i can do it. i have good news and bad news! i will start with the good news, it is possible!! and now the bad news we have to write the cnc data new and we have to do a test with one of these knobs! i called Alpine here in Germany and it takes two weeks to get the knob, so that is not a problem! but what are you willing to pay if we do all this? give me an offer and i speak to my Dad because he is doing the cnc stuff!
