Brakes better work now

Can anybody help me out. I bought a new Tuiff-Stuff brake booster and master cylinder. I'm having the hardest time mounting it. I stopped. It shouldn't be that hard. I connected the rod to the brake pedal. The 4 bolts on the firewall were about a 1/2" away from the bolt holes on the bracket. That's about 2" Do they make a mounting bracket for this converision and where would I buy it? :coffee2:
