Power steering on a '73 Dart Sport?

Hi all,

I have a 1973 Dart sport with front disc brakes and back drum brakes. I'm considering installing a brake booster, for extra stopping power and safety.

But i keep wondering. Is a brake booster on that model neccesary? Or are the manual brakes strong enough? And if I would choose to install it, where can i find a fitting booster (I live in the Netherlands) and would it be an easy install for a beginning mechanic?

Thanks four your views and opinions!
