^^^Ignore this. No he can't. The u-joints in the driveshaft don't have enough articulation.
You can run the axle the way it is with the proper caster (pinion will be close to horizontal), but you need a double-cardan
for the travel you are shooting for.
Remember the front driveshaft isn't spinning unless you are in 4wd and the front hubs are locked in. The pinion does not have to point directly at the output flange in all circumstances. To have the best vibe free conditions it should, but you need the alignment numbers to be correct, since you will be driving in 2wd (at any speeds) ALOT more than 4wd at 70 mph with the front shaft spinning.
In an ideal world, the C's would be rotated to the correct caster when the pinion is directly pointed at the tcase flange. But that's a TON of work that's not necessary, at all.
