i looked into it a while back and have previously had obne in a stanza which is more difficult. you could cut the upper mounts from the 4 link off the 200b diff and add them to the 31 diff, then just move the trailing arm/strut mounts in a bit to line up with the 200b body mounts. they are just a little wider from memory.

If you dont have low offset/wide wheels you wouldn't need to shorten it as it's only about 50mm wider than then 200b diff which standard leaves you something like 75mm outer guard clearance with stockies
