Lay under the car and undo the 12mm bolt going through the shifter.
Get inside the vehicle remove all the interior pieces surrounding the shifter. Take a flathead screw driver and remove the spring (looks like a metal retaining clip, until removed)
Yank the stock shifter.
Remove rubber boot off bottom and place on the B&M
Remove the OEM bushings off the bottom of the stock shifter and place on the B&M
Use the lube B&M supplies with the shifter, apply it around the rubber rings on the B&M (wax that shit, more the marrier)
install in reverse order.

Enjoy

The replaceing of the spring is the hardest part. I can have my shifter full out adjusted(pacesetter adjustable) and in in about 15 mintues now. :D

hardest part for me was getting the b&m to seat all the way down, thats why I said wax that shit.
