The TRW pump is similar to the Federal pump. You might want to look that up. But generally speaking, support for the Federal style pump is very scanty. The Saginaw pump is easier to find, has better parts support, and is actually a better pump — it doesn't struggle to keep up with rapid turns of the wheel. I don't know what motor you have, but you can buy the pump and the brackets for a small block in many places. I have a slant six and had to scrounge used brackets to convert.
