This is one of the best set ups for Manual brakes for the early 64-72 Mustangs going Coyote or Godzilla and you just do not have the room for a Hydroboost. I have driven several early Mustangs with all different power levels and combinations and hands down this master cylinder works excellent. It is not like you are pushing against a wall or going to pull a ham string when you have to jump on the brakes.
