This change may be of interest to me in the future.

Here's a pic of where to find the stamping, bottom LH corner of housing as you look from the back. Took a bit of cleaning to see, but this one is clearly 2.88:

the W126 diff is slightly wider, measured from the faces where the half-axles fit, O/W the housing looks the same. The end result is that the spacer rings for a W123 have to be thinner, I believe that is the direction we had to go after stuffing a 126 diff into my 300TD. THe camber was out and tire wear set in before I figured it out. After the right spacers were installed it is OK, in fact right on, and I still drive the car with no unusual tire wear (after replacing 2 rear tires

)
Here's a Ratio list I made up:

Well, decided it won't go in this winter and I'll find another one by next summer so...., this one's gonna go.

Anyone interested, email me. Was hot-tanked, cover removed, everything checked, nice and tight. Comes with a flex-disk I couldn't get off at the yard (and don't feel like taking off now), cover was separately cleaned then re-painted while off. Installed with Ultra-black sealer.

Here's pics

Will also post in the Parts for sale forum as the more appropriate place to sell something.
