Replacing Gear Shift Knob

Hi, I hope this is the correct forum to ask this. I am looking to replace my stock 98 shift knob with one from a 2001. I got the boot off without any problem, but how do I remove the knob from the shifter? I do not see any screws or fasteners on either my old one or my new one. It looks like it just pulls off, but I don't want to break anything by yanking on it. Any suggestions? Thanks
