Common sense dictates that all that is required are a few shims, size I would guess at 5x10x0.5mm, or whatever size the output shafts on the diff are x the diameter of the bearings x 0.5mm as thats a common size. Just use 2 or 3 until there is no or very little back & forth movement of the diff between the mounts/braces.
