Mine was a complete swap with m/c, prop valves and booster.  Some say
that you can retain the original parts, but the pedal feel will
suffer.

I don't know if this will affect you, but (if you go to the 16v
booster) on my 75 car the pedal cluster needs to be changed to a later
type or (what I did) the actuator shaft of the new booster needs to be
extended about 1-1/2" to mate with the old brake pedal configuration.
Then there is the brake light switch that needed to be rigged since
the 16v m/c has no pressure switch port.  I swear, it's all worth it.
You'll know the first time you hit the binders!
