CPP's Series 500 steering box isn't the same one in your grandpa's car. Although it does feature a universal three-bolt GM bolt pattern and a 3/4-inch 30-spline input shaft, the ratio is much quicker at 14:1. It also features a modern spool valve for razor sharp steering response. The fluid lines are 11/16-18 and 5/8-18 inverted flare, making them leak free; CPP provides the necessary hose conversion fittings so your original-style hoses will work.
