Brake assembly Manual brake vs power brake

[Moprr]

Just wondering what the difference is from a brake assembly from a manual brake car to a power brake car.  Can they be swapped? what needs to be modified?  I have a manual assembly and someone needs an assembly for a power brake car.  Just want them to be aware of the difference Thanks.

There's two studs coming out of your firewall above your manual master cylinder. They have to be removed and drilled out. The reinforcement plate is different as well.
