Help!! Power steering pump and bracket identification

Thanks, I've got the pump and brackets identified now...70 and up small block with Saginaw pump. I am missing the triangular piece of bracketry and have another post not far from this one with the web address to show what piece I need. I would be eternally grateful to anyone who has one and would be willing to part with it.
