Front and rear unis are new standard XF, so they would be the same as on the borg warner. So Im thinking in light of what you are saying that it is a miss-match. What do I have to do with the rear uni to make it match to the 9 inch? Who did you see to fix it?
If you have used an xf uni you have the wrong one in the rear.There is only a small difference in the diameter of the uni cap
that goes into the diff yoke .The xf uni caps will be slightly smaller.This will be enough to cause the vibe..Your best bet would be to go to a driveshaft place rather than mucking about with spare parts salesmen that dont have a clue what you're talking about..
A good driveshaft place can usually fit your correct uni's and balance it so you know it is then perfect..all for a reasonable price.
Something else to watch since you have had the diff conversion done is to have a quick look at the pinion angle.This can also cause a vibe that can be hard to trace.
Looking from the side of the car the front of the diff should sit horizontal to pointing slightly down..
