The alignment of the axles to the diff isn't "
that" difficult or even precise. I put 2 from PNP onto one of my wagons, and even though they measured slightly different from groove to other end I used the same thickness spacers and they worked fine.
At the very least all you would need to do is go to Mercedes and buy several spacers. And if you measure first you would know the thickness. If not, buy several in varying thicknesses.
If I may be so nauseating, there is some "
wiggle room" with this.......
Just sorry you are having this kind of trouble!
