I enjoy the direct feel of manual steering on an A-body. But if you do feel you need power steering, I recommend getting a Borgeson fast ratio power steering box with a Saginaw pump. The Borgeson setup will provide a more modern, less over-boosted feel, and the Saginaw pump is superior to the TRW or Federal pumps on many A-bodies — it can better keep up with rapid changes of direction, and parts are more readily available. The blue convertible in my avatar has the Borgeson setup, the copper fastback is manual.
