Some of those F350s actually had a Dana 50-Sterling 10.5 combo... A lot of people mistake them for a 60 front. They're also unit bearing which isn't as stout as the older 60s. And gus is right, the drivers side tube is very short.
It's not bad equipment, it just isn't as good as a set from a CUCV and therefore doesn't merit the same value. IMO, you'd be better off to try to aquire the CUCV axles instead and pay $500 more. You'll have something we know will work and you get the rear locker for free in the process.
