If you are going to have to move the bare chassis around a lot before putting the body back on it would be a good idea to buy or build some rolling platforms to put under the rear wheels so they don't have to turn.
Unfortunately it sounds like you are going to have to take the rear apart again to deal with the differential yoke problems.

Did you change out the Ujoints just now? Sometimes, if the outer Ujoints are installed incorrectly, the bump for the grease fitting will hit the spindle shaft. Seen the same thing happen on the drive shaft where it connects to the diff. My fault, both times.
Doesn't matter how much of a hurry you are in the first time- you will always find time to do it over.
