Joe, I put an open driveline in my '37, but I used '55-'59 1/2 ton components. The wheels do sit a little forward in the rear fender openings. I've heard about reversing the springs also, but when I measured mine they sure seem to be symetric. I may be wrong, but I don't think reversing them will help. Mine measure the same from the center locating bolt to each end. If you find out any more about this or try it, be sure to let us know what the results are.
