NO parts from your 250 D50 ttb will swap with your current D44 ttb. The center pivots most likely are the same, if you wanted to use the whole beam, but you are on your own for coil bucket and shock mounting.
To 8-lug your D44, you will need backing plates, caliper brackets, calipers, etc., and the 8-lug hub/rotor assembly from a '78-'79 F-250. You can keep your existing spindles and bearings (if they're serviceable), and you will need to use your spindles (different ball joints). Of course you will need to have your pumpkin re-geared to match your rear end.
The rear end is a bolt in other than different U-bolts (the 10.5 has a larger axle tube diameter). You will also need your driveshaft shortened about 3.5" IIRC. Have the driveline shop put on a yoke that matches the rear axle U-joint to eliminate goofy conversion U-joints.
Sorry it means you'll have to do a little more work, but it will be worth it to keep from scattering your drivetrain on the Tarmac, or worse, on the trail! Good luck with your build!

The t-case output is the same to both axles on any chain-driven t-case so even if the output ratio is as you said, the .01 difference still exists between front and rear axles. The only way around this would be with a t-case like the NP203 which has an internal differential that will compensate for the discrepancy. A viscous coupler on one of the driveshafts would work as well. That's why Bronco's that were equipped with the NP203 were available WITHOUT front hub lockouts... so basically full-time 4WD.
