so recently i bought a new knob and took off the stock knob, which btw you just pull really hard up to get off. and than there was a plastic piece that is sooo hard to get off, so i cut it off with a saw.
You should have done a howto on the shift knob. I see that question come up alot. I myself am very curious. I know you just say pull hard but I like pics of each step. BTW I like the new height and knob.
