I need help with brackets

Ok, I wanted him to ask that, but he forgot to mention that it's the power steering brackets we're working with. We pulled the /6 and dropped in the 273, but the donor car had no P/S hooked up, so can the brackets from the existing Saginaw pump from the /6 be adapted to fit a small block or are they different? Hey, I'm a big block guy...I don't know. Thanks!
