Be prepared for the oem knob to get damaged
Mine ended up in 3 pieces
Had to use a pair of grips on the shaft and a bigger pair of grips on the gear knob (wrapped in a towel) unfortunately it wouldn't budge so enlisted help from a pal, I held the grips on the shaft while my pal twisted the gear knob. Lots of loctite holding it in place and unfortunately it split under the force
Lots of swearing but we eventually succeeded however the oem knob was toast by the time we got it off
