69 SBC Steering Pump Brackets

Ok I've searched and now I'm giving up. I have a 69 with power steering and all the parts...I do not have any of the mounting brackets for the power steering pump. I also do not want to pay $100 for new ones...this is a driver not show car...so I wanted to go to pull a part and see if I could pull the brackets from another car...does anyone know what brackets (looks like I need three) from what year and make cars are interchangable with a 350 with a long water pump????

thanks!!!
