I have a 2.88 diff I pulled from an '85 to put into my W126 with the 3.07.
I thought it was a direct bolt on. Are those flanges different?
Please tell me it ain't so!

He meant to say "2.47". The 2.88 came from the '85 diesels and it is a direct swap.

I have put the 2.88 in the SD ('84) and it is, for me, a perfect setup.

I would only recommend the 2.47 to those who do extensive high speed driving (70 mph +) on relatively flat roads and will suffer the difficulty in launching the vehicle from a standstill.

The 2.47 does have the larger case and requires a change of flange. It also may require a change in axle shafts but I am not certain.
