So, the steering gear can't be adjusted, right? I believe repair parts are available. One of the antique parts vendors might have them in stock, or you might find some NOS parts somewhere like Hemmings' Motor News. Try a post in the "parts wanted" forum- - - -some of the hotrodders who have converted to a different steering system might have a good steering gear cluttering up their junk pile.
