basically, fabrication will be required to suit nearly any car. the box requires a reinforced bracket to hold the pedal box (so welding and drilling is required). the boosters are wilwood items, and connect directly to the pedals via ball-jointed adjustable threaded rods. The brake pedal runs 2 boosters (1 for front calipers, 1 for rear), and they have a brake bias bar to adjust how much pressure each booster is recieving.
it is a little difficult to explain without showing you in person, but i hope i didn't confuse you further.
