Roland, I finished installing your power steering unit on my 1964 Ford 4000, it works wonderfully. With the one arm Ford loader I had to install a GM power steering pump instead of a Priority Valve. (I tryed to get a couple of pictures of it, however, their kind of dark) I've had full Hydraulic steering on Combines and John Deere tractors before,but none worked any better than your unit.
PS I'm glad I waited for you to recover and build my unit. May God Bless You and give you a complete recovery.
Have your tractor's picture and information engraved in stone just like this one! Size varies since each stone is different, but approximate size is 13"x15".
