260Z with ZX Booster

My 260Z was built in August so I believe it's a late model 260Z.  In an effort to restore the brakes, I have a ZX Booster with a ZX Master Cylinder.  The booster mounts without having to drill any new holes.  I read a bunch of posts and I recall installations requiring to flip the booster upside down to fit.  I did that and now the last 1" of pedal travel (before it hits the brake switch) has a noticeable "stick".  It sounds like a thud and feels like the boost and/or rod are getting hung up somewhere.  I checked around the linkage and nothing is interfering.  The rod to the booster seems to attach to the brake pedal arm straight.  I'm thinking the booster needs to be re-installed in reverse to get better alignment?
