Disc brake help.

Would 67 gto disc brake cars come with a smaller or the larger power booster? I ordered this set and it came with the smaller one. Fits 65-72 Gto. Are there any advantages to a smaller or larger? Or will there be no difference?

Hard to say because you don't have the specifications, but generally a smaller dual diaphragm will produce more assist than a larger single diaphragm.

Does not make a difference, will give you more clearance with the valve covers.
