A couple things here; one, no Ford ever came with a locker from the factory, the best they came with was a trac-loc limited slip. If you happen to already have a trac-loc and money is a huge issue, go ahead and replace the clutch pack and use it. Truth be told though, they're not a very good limited slip. If you want a limited slip you'd be much better off buying an Eaton. Even better, and less money, buy a locker for the front. I've been running an Aussie locker up front in my D44 TTB for years and it has held up really well, even stood up to broken axle shafts.
The other thing, and much more important really, is that the D50 TTB will NOT bolt up in place of the D44 TTB. If you take a good look at the D50 arms you'll see that they're shorter than the D44 arms, meaning that it is definitely not a bolt on deal. Every time I've seen this discussed it has pretty much came down to a consensus that swapping in a solid D60 is cheaper and easier, believe it or not.
That's not to say that the D50 is completely useless. The only thing that you can use out of the D50 TTB is the stub shaft, and that's actually a really good upgrade for the D44 TTB. The stub shaft is the weakest link in the D44 TTB, and it sucks because it's retained into the diff by a c-clip. Replacing it with the D50 stub shaft removes that weak link, making the next weak link the locking hubs. That is a very good thing, because you can replace a busted hub in fifteen minutes on the trail. Here's a comparison pic between the puny D44 shaft comapred to the beefy D50 shaft.

See? There is a HUGE difference. I've broken hubs, broken axle shafts, but never that stub shaft. If you want some more pics from the swap check out this link to my Supermotors page.
