I have an OEM shifter knob from a 2012 6 speed that I've been considering putting into my 2016. The bolts for the 2016 are longer so they bottom out on the 2012 shift knob before they're tight. I have to find the right bolts. If you get the bolts with the shift knob you can just use them. Also, the leather boot is completely different. At a glance it's not going to fit the 2012 knob very well. It may have to be modified but I haven't tried to yet.
