Chuck Harmon...did you ever do this...

I have closely followed the posts of others interested in adding power steering to their C3's. Big blocks with headers seem to pose a problem with the Steeroids system. Personally, I just don't like hanging more hardware at or below the front of the frame. I have also never been impressed with the original horizontal hydraulic ram system of the stock design.
The Corvette Steering system uses a Saginaw box like those on many other cars not using a hydraulic ram. The mounting bracket to the frame has been the problem for others in retrofitting these to our C3's. Corvette Steering has made the adaptation. I will be using the new and very small power steering pump as found on new GM cars like my ZO6. The owner, Tom, measured the unit and found it to be virtually the same as the manual box regarding the distance from the frame's mounting plane to the point closest to the engine. I don't want to have to dimple my headers to make it fit!
With brackets, pump, steering box, hoses, pitman arm, etc. it should be $200-$300 less than the Steeroids setup.
Would like to know the outcome.
