      Make sure it is a dual booster in the smaller sizes or you will be giving up brake pressure and require more effort to stop.

      Mike has a good point. Single 11" boosters and dual 8" diaphragm boosters have close to the same gain at 95 in^2 and 100 in^2 area, although some would argue that the single diaphragm unit gives better feedback and feel. A dual 7" unit is about a 25% reduction in gain at 77 in^2 and will require a corresponding reduction in master cylinder bore size or pedal ratio, assuming you have the pedal travel to accommodate it. Similarly, the dual 9" units are about a 25-30% increase in gain over the 1-11 or 2-8 units...but if clearance is already an issue, definitely measure twice.
