From mbturbo.com there's a rear diff compatibility chart and lots of fitting/removing information. One thing I can't see though is what parts are interchangeable between the different diff casings. My W114 diff has ring of six bolts around the driveshaft while the W123 diff is smooth in this area. Photos below, sorry about the grottiness.
Would it be a case of taking everything out of the W123 casing and fitting it in the W114 diff body? Or can the W114 driveshafts just slot into the W123 diff splines? I've a feeling there would be a sealing ring issue if I did the latter.
Thanks
