Looking for a rear diff to fit my 92 W124 300D with a ratio of 2.87 or close ive got a 3.07 in it now and want to get my rpms down. Let me know if anyone has anything out there. Thanks

I have a 2.65, trade you?

I have a 210 mm limited slip that was going to be used in my 97 SL 320 but it turns out mine is a 198 MM, no idea if the 210 mm will fit your car. My notes show the casting # to be 126 351 12 01 but I can check the actual diff. I'd be looking for $ 300 + shipping.

While I haven't done it to this specific diff, a ring gear spacer will allow you to use higher number gear sets.

I bought it a few months ago from this ad.

This is a 210mm ring gear and 1.3l case. FWIW - The last 2.47 lsd w126 diff I sold had it's carrier fitted into a case for a w124.

Yeah, the one I have is a 2.65 ratio.
