I have a 85 f150xl 4x4 longbox and no rear driveline its a one piece with a slip in yoke. Can't find one any where around here and new is way out of my budget. It really sucks as I work for a auto recycler and can't find one.
Sorry not much help...but there's a notorious ebay seller from lewiston, just saying. New shaft is $200ish...after shipping, I doubt it would be much cheaper.
