swapping 240 brake booster with 300zx

[got chub]

i got a full Z brake upgrade booster, MC, calipers, SS conv. lines, R33 cables, ebrake assembly, hawk HP+ pads and fresh rebuild kits. now i have everything that i wanted painted and ready to go on. my question is the brake booster. how do you get that off. i know it goes to the other side of the fire wall but i haven't looked to see how far up it is. so i guess I'm asking can i get the nuts off it with out have to remover any dash parts?

thanks in advance
