From manual to power brakes

I reversed what you are doing, The pedal assemblies are the same. You will however need to get a different push rod that goes from the brake pedal to the master cylinder. The power brake push rod is longer.. Or buy a universal adjustable one.. I would just post a wanted ad here on the site for that part itself.

Everything else inside the car stays the same, Its all the components in the engine bay you will need. Also dont forget to find the brackets that help support master cylinder and booster. This helps it from moving around as you push on the brakes and supports the assembly since its a lot of weight hanging there.
