The ring gear diameter of the 107 diff is 210mm, and that of the 123 is 185mm. Both diffs share a common mounting pattern, but the 210mm diff is wider than the 185mm. If the half-shafts from the 107 are used, it will all go together. Yes, the pinion yoke will have to changed to the one from a 185mm diff.
