Well, I just typed this out to explain to someone who pm'd me how to do the mod, so I figured I'd put it up here for anyone interested:
To install- first take off the stock shifter.
To do this, take off the silver part on the bottom (push it down until it comes off, a screwdriver may help). Then you'll see a goldish ring type thing. Take this out (away from you). The shifter should slide right off then.
Then, take off the silver ring around the shifter (takes a little force). Take the bigger black tabs off the ring (take tape off then bend until they snap, leave the smaller ones, so that the plastic will snap back in).
You have to kind of stuff the shift boot in around the gaps in the edges, and then reattach the silver part (may take a little time to align).
Then just put the Momo shifter on (make sure you have allen keys).

Finished results:

 

Lemme guess, camera phone...

Good to see that you finally pulled it off... and now for the faux clutch pedal.

 

no no no, it's been done for many months now, but I just typed it out to reply to a PM and figured I'd help out anyone else
Yeah, I do need a faux clutch, I tell really ignorant people (women, hehe) that the dead pedal is a clutch
