Thats a pretty broad question, to help you, tell us what engine you have, post a pic of your curent access. drive set up (alt only ???) to help point you to a pump for your application. Then tell us what type of front end is it based ? Custom ? Must II, BMW ?
Sorry but I dont know about the NAF car you show as having. My West Coast Cobra uses a GM saginaw pump and a Ford PS rack (T-Birds or Mustang II type). The big block cars benefit more from PS than the small block cars due to engine weight on the front axles when cruising around town. If you are running a SB with alumunum heads for example I would say PS is a complete NOT NEEDED.
