I did it.
Pull the column out, and pull the front seat, so you have more room to work. I laid upside down on my back in the car to do mine. Just have a friend hold the booster in place so you don't push it out when you are first installing it. I did mine myself, what a PITA. Anyways, once you get the 4 bolts in at the firewall/booster, don't tighten them all they, because you need to put the bolts in at the top of the pedal box where it bolts to the cowl area. You need to move it freely to line it up. Then plug in all your wires, and stuff like that.
(Make sure you put that black spacer back in. It goes between the firewall and the pedal assy. I forgot mine, then realized I need to put it back in. I got it back in without removing the whole assy, but that was a nightmare. Pulled the column again, had my Dad pull the booster out as much he could so I could slip the stupid spacer up in there.) This allows more pedal travel. It is black plastic, and breaks very easily.
