Found their site and clicked on the R170 section by mistake, but found a great looking red and silver shift knob. I'm trying to find out if it will fit my r171. I tried to register as a new customer, but kept getting rejected becaus of my birth date. I input it the same way as the sample, but still got rejected. I put in the same date as their sample - rejected. Finally tried calling them on the phone (fun!) and got a german message. HELP!! I want that shiftknob IF it fits my car.
