Super55,
You will need a power steering pump to run the booster no matter what.
The option you will then have is converting to a power steering gear box instead of the manual. The thinking is you will have the pump for the booster, so may as well use it for power steering while you are at it.
The Power steering pump can be run from a second grove on the crank pulley if you can find one, or there are many other options.
Check my pictures for one, and I can sell the bracket I made, as I don't need it any more.
