How about this. When I bought my '88 F-250, the previous owner had removed the center pivot of the TTB and welded the two halhes together to make a solid axle. Don't try this at home!LOL! It took me a few weeks to find a 60, but I got one complete with hubs and all for $1000. I don't know where it came from, my buddy that works at the local city garage found it. Good Luck!
