Power steering pump??

Greg I believe your pump is the Federal pump so you'll need brackets for a federal pump to a small block. I didn't know there was any diff. with pulleys but according to Dave's pics there is. Might be just as cheap to get another pump with the correct brackets and pulley.

BTW: You can use the newer Saginaw pump. I used it on my 68 Cuda and it works fine. found it at a swap meet for $10 with the brackets on it.
