Make sure you bench bleed the master cylinder and bleed the entire brake system after installation.
Since you are starting from a clean sheet of paper you might want to consider a Hydroboost system instead of the vacuum system if you have a power steering pump.

You’ll need to change the booster and master cylinder. You’ll also need to change the brake switch lever. This is actually one of the best up-grades you can make to the car and it is pretty easy to do.
You will need to open the hole in the firewall as shown below. This is easy since the inner bracket was made to fit both power brake and standard cars so you have a built in templete. When you look from the inside under the dash you'll see what I'm talking about.

Thank you
So In addition to making the hole larger I guess a 71 power brake cyclinder and a power booster/ and vacuum hook up along with the brake switch (is that for the stop light ) is all I need ??? I had heard I didn't need to change the brake cyclinder. Any extra holes need to be drilled ???
thanks again

Yes you will need to change the master cylinder! The power brake and non power cylinders are different. You'll also need to purchase the fitting on the back of the intake that will supply the vacuum to the booster.
You can do this with a T but it would be smarter to do this with a new fitting. The P/B fitting has a didicated hole for the brake vauum supply.
You will have to drill two holes. I have some notes on this where we did a conversion about 15 years ago. . . somewhere. I don't think it is on this machine, so I'll have to look on Tuesday to see if I still have them. For the most part I think I've covered it.
