First of all, http://roadsleeper.vwmafia.net/shifter.html is an excellent webpage on how to remove stock knob/boot and install a stock knob/boot that is preattached from the manufacturer. This was only good up to a certain point. After I got it off, I said, "What do I do now?" That's when my handy pocket knife came in handy. I'll explain later.
For those who are interested, I took some pictures and did a write up on this EASY process. Took me about 45 minutes to do. Take 10 mins off for a crap break. Fried chicken in the morning is bad on the digestive system.
DISCLAIMER: YOU F**K UP YOUR CAR, IT'S ALL YOUR FAULT. DON'T BLAME ME OR MY SORRY INSTRUCTIONS. WE ARE ALL ADULTS HERE. USE YOUR BEST JUDGEMENT. Here goes...
1. First of all, work in a nice place. You'll feel much better. Anyway, you want to remove the trim ring around your shifter. I used two hands and placed them underneath the "ledge". You can feel it under your fingers. One was occupied at the moment with the picture taking. Just lift up and forward at the same time until it "snaps" out. You'll hear it.

Here's me pulling it up. Ohhhhhh, ahhhhhhh!
2. Once the boot is pull all the way up, you will see a tiny brass ring. This needs to be cut and removed. I used wire cutters for this process. Make sure you take your time and don't mar anything.
Picture of brass ring.
You want to cut the piece of the brass ring that sticks out in a square shape. It take a bit of effort but it will deform and break.
Once the ring is broken, you want to spread the ring apart and remove it off from the shifter.
Here's the ring in my hand spread apart.
3. With the brass ring finally off, you can go ahead now and pull straight up on the knob and it should come right off. Here's me doing it.
4. Here comes the part where I was stuck between a rock and a hard place. How do I remove the boot from the shifter? I'm sure there are MUCH better ways but this is how I did it. Being lazy as I am, I took out my trusty Benchmade knife and cut around the leather as depicted in the picture. It took about a minute to do.
Before and after pictures...
5. Next, follow instructions that came with the SCR adapter. It is available from their webpage. Very simple to do now. Here are some pictures of the install and final product.
6. Here's the final installation process. Hang on, we're almost done.
Put the boot back on the shifter the same way you took it off the first time. Don't "unfold" it all the way yet. You will need to play with the hex screws on the SCR adapter and knob.
Next, follow the instructions that came with your Momo knob. Very easy. You will first need to install the sharp hex screws into the knob. This will of course be used to tighten it down to the shifter. Just get them started so it will slip on easily onto the shifter.
Oh, be sure you slide the Momo threaded ring onto the shifter before putting the knob on. This is how it should look with everything on but not tightened down.
You want to position the knob how you want it and slowly turn each hex screw on the knob one at a time until it tightens all the way. Make sure it's how you want it positioned. Make sure they are tight so the knob won't turn on you. After that is done, screw the shiny threaded Momo engraved ring onto the knob to cover up the holes.
7. Position the boot how you want it and carefully lift the boot back up to expose it's hex screws. Pull the adapter up until it hits the bottom of the knob. There's only two screws on the SCR adapter. You can use the allen wrench supplied with the shift knob. It fits perfect. Tighten the screws down until they are tight. Now you can reinstall the shift lever ring. The front end goes in first and then snap the rear back down. Simple.
8. Work your gears to make sure you can shift.
9. Go for a test drive.
10. Grab a cold one.
Here's the final product.

GOOD LUCK!!!
