For 10" of lift you are going to have to clock the t-case(also making a new crossmember) and most likely the axle too.

A E4OD is the longest driveshaft for a F350, but I would venture to say it will still need to be lengthened by about 6"

I would be leary of the missing drive shaft, like the axle has different gear ratio or the axle is junk
