Anyone have a diagram for a brake booster set up?

I have the offset bracket that goes between the booster and firewall, and the stiffener support brackets, but I bought a new booster and there is not a location to connect the support brackets. I also have concerns about the master cylinder that the part store ordered for me. The top usually has one big bubble in the back and one small bubble up front, this one has two small bubbles, nor do I know if the same size of brake line will fit it.
