The only new parts are an adjustable brake push rod, a new master cylinder with the correct size bore, and a firewall stiffening plate.

The booster and cureent brake push rod and linkage will be removed. The new push rod bolts straight to the brake pedal arm in a different hole than the old linkage.

The firewall stiffening plate from a manual brake car is best, but your existing one (attached to the back of the booster) can be cut to work.
