How to replace my 6spd Shifter Boot

[ETChipotle]

I have a 2000 Superduty XL manual tranny 6 speed that I bought about a year ago. The shifter boot hard plastic base was busted up it the truck's previous life so I finally bought a replacement part at the dealer.

Problem is, I'm not sure what I need to remove to replace this thing.

I got the old hard plastic thing with 4 screws removed fine, but now it's hung up on the shifter. It doesn't look to me like you stretch the new boot over the knob, but I could be wrong.

It seems like the existing boot is tucked up into the sleeve of the shifter lever. My first guess is that somehow I could take off that sleeve and replace the shifter boot, then put it back on. But I can tell how it's on there.

I'm a little nervous to go ape on it and then have to buy more parts. Wouldn't want to hurt my little truck.

Help would be much appreciated!
