Thank you for all the responses, I have contacted Power Steering Services in Mo. and will be shipping the box to him soon. I have to many other projects going to learn the workings inside this particular unit. This is my weekend driver so it must be right the first time. Just a little info, Early Ca. built 69 convertible, Daytona yellow, standard white int., 327, 350 auto, a/c, p/s, p/b, p/top. Lots of miles but no rust.
