Just snagged a motorhome 727, the only thing i'll need is a driveshaft?

Well, now i have two BB 727s except they're both short tailshaft 727's. One is definetly out of a motorhome because it came with the motorhome 440 i just bought and the other is still a short tailshaft anyway.
Neither had a drum brake on the end but the one with the 440 has a slip yoke and a cut section of driveshaft.
I did a bunch of searches and i'm led to believe all i'll need to really make this work in my Duster is a driveshaft with a slip joint in it? I'm assuming a 4x4 driveshaft will work but can anyone confirm?

I reckon the torque converter is also wildly inappropriate for a small car, i guess it depends on what motorhome it came out of but is it safe to assume this TC is useless for my application?
