I use a 2 ft. extension on the four 15mm nut's that hold the hydroboost unit on to the firewall, and I use a wrench on the brake pedal bolt, I don't pull any of the dash apart at all. The brake pedal bolt is the hardest part of the whole thing, you can only turn the bolt a little at a time, but with some patience it's no problem. Also you don't have to hold the nut on the brake pedal bolt it is welded on from the factory.
