to take it off, you have to feel around the top of the shift boot for a plastic ring. turn it to the left about 1/4 turn. then you can push the boot down. then pull straight up on knob. it pops right off. its an odd set up and to put a custom one on you have to figure out how to fab the aftermarket one. or buy a new shift boot with a threaded top. pm me if you want to know how i did mine.
The post by scagnetti76 describes it, it is only held on there by the lock ring, because the lower half the factory shift knob has a lock to it, which when the ring is turned a quarter the way, will allow it to come off.The aftermarket knob i have has two peices to it. They screw together as if they were to slide the boot into it then tread together around it. If that makes any sense. But how do i get the boot off of the knob presently. Becuase the knob which is on there atm, looks like the boot comes all the way up and is built right into it?
