IIRC the arms on the Dana 50 are longer and require a different bracket than the Dana 44.
Any reputable lift company should be able to get you the drop arms you need. Give them a call.
If you can find a donor F350 with a solid axle for the right price, go for it. They aren't cheap around here because everyone knows what the front axle is worth ($600 - $1000).
I shop in the salvage yard.
