I just converted my '51 1/2 ton from roller bearings to tapered. I recommend it very strongly. The steering is smoother and I have no doubt it's safer. I'm not sure about the availability for 1 ton. Check Brothers and the company that used to be Chevy Duty, Classic parts of America. The latter was $125 for my truck, cheaper than Brothers.
Hope this helps.
