Do a search on adding a Hydroboost to a manual brake car. Hydroboost attaches to the firewall just like the vacuum PB cannister. On a manual brake car the rod from the MC extends through a hole in the firewall and attaches to the brake pedal lever. The brake pedal lever has two mounting holes. On a manual brake car, the MC rod attaches to the top hole and the bottom hole is used to mount the brake light switch. On a PB car, the rod attaches to the bottom hole and the top hole is used to mount the brake light switch. You have to modify the firewall hole for a PB conversion since the rod is now lower. Also, you have to change the firewall hole mounting bolt pattern. The instructions for converting a manual brake to Hydroboost will have the pictures you need.
Converting to PB, means working on the inside firewall high up under the dashboard. There's not a lot of room. PS I mentioned Hydroboost. I'm adding it to my car just to make room for my BB valve covers. If it weren't for that reason, I'd continue to use the standard factory vacuum PB cannister. Also a vacuum PB cannister is a lot less expensive than hydroboost.
You'll need to change the brake lines from the MC to the distribution block. Also, for PB, the MC has a 1 1/8 inch bore. The manual MC has a 1 inch bore.
