Or is there enough play/space in the center diff output shafts to let this setup work? I'm scratching my head, so I thought I'd ask you racers for some practical advice.

Thanks in advance.

I did the same upgrade a few weeks ago and found the same problem.
I solved it by adding some shims on the shaft. The same shims that are on the shafts on the weels between the bearing and the hex from the hubs.
I needed to ad 6 shims to eliminat the play.
