Adding booster to 69 Fury III drum brakes
 

I'm looking at buying a local Fury III, it's been such a long time since I drove anything without a power assist on the brakes I'd forgotten what it's like. What parts would I be needing to properly convert unboosted drum to boosted? Looks like remanufactured or pattern part boosters are easily available - where would I draw a source of vacuum from to 'power' it, and what other parts would need swapping - master cylinder too? Pedal linkage/hardware? It's a 383 with an aftermarket 4 barrel, Edelbrock I think.

It is fairly easy. Basically Remove/Move the master out of the way carefully.. Remove the reinforcement plate on the fire wall. Then bolt the power booster to the fire wall with a new gasket. . It should have linkage already to bolt to the brake peddle and have studs for mounting.. Hook the master back up. Hook the booster to the back of the intake vacuum source.
