Trust me u CAN get it off with just twisting. put a towel over it and twist like **** to the left while holding the gearstick with the other hand. i've done 2 gearknobs without hacksaws and both were off within about 60 seconds.no chance of it just twisting off had a look at the remains hacksaw is what you need for it just be very careful. I may whack it as a tutorial if its not been done before
