Perhaps not as easy as some suggest. While the p.s. gear doesn't care what p.s. pump you have, the hoses do. You need hoses w/ the correct fittings, or change the valve body on the gear to match your hoses. As I recall, TRW pumps were inverted flare h.p. fitting, while Federal pumps were O-ring fitting (Saginaw too?). The fittings on the gears varied over the years, perhaps in sync with the pumps. Return hoses varied in ID. Of course, some people can make hoses from scratch, or if you have old fittings. The 1965 h.p. hose had an in-line reducer, at least in SB and BB engines. Re brackets, perhaps not all combinations work since the later alum water pumps are ~1" thicker. They also don't have the hole required for the TRW brackets. The Bouchillon web site sells brackets. It appears the TRW pump was never used with the alum w.p., so perhaps the reverse is true for the Saginaw pump (never used w/ cast-iron w.p.?).
