Dan,
If booster mounted with 4 studs you'll probaly want to move master to top holes,my 79 malibu was that way originally I installed with master in center of the four holes brakes worked OK but not great found out later that manual brake setup had master mounted on the top set of holes,increased ratio made huge difference in braking power.
MAKE sure you have pushrod retained so it can't come out,some masters have just a countersunk area for the rod to set in I usaully drill that a little deeper so there is absoulutely no way for the rod to come out and fab something so pedal can't pull rod out of master anyway.
I don't want to read in your N/D stories about the your manual brake conversion gone bad and crashing the family wagon.LOL
I like reading your stories,good luck with your project.
Most of time if rear is @ stock height or lower w/factory sway bar,body roll should'nt be bad. Mike Taylor 3601
