Sorry about the late response .... could be that all the gang were out over the weekend ...
Anyway, I have not. But I always ask the question: Why do you want to?
If you want to do it because you want to do it, or you have a medical/physical reason ... then by all means. But if you think you need to do it to get "better" steering .... In my own limited experience on three restorations, I have found that rebuilding the steering box, replacing the tie rod ends and king pins, and getting everything in adjustment (all things you'd want to do anyway) provides steering *almost* as easy and comfortable as power steering at a fraction of the effort, expense and fabrication. In my current truck (1949 3804), I routinely drive 60-65 mph with original steering (adjusted, naturally). I even run bias ply tires. Steering is solid. Even at a crawl in the parking lot, it isn't too bad. Not one finger, but certainly one hand.
But like I said, if you *want* to do it, then have at it. But you don't *have* to do it for better steering -- just rebuilding and adjusting what you already have will get you 85 to 90 percent of what power steering would do for you.
Food for thought.
