Question 2004 SL600 Differential Help

I am trying to buy a LSD unit for my 2004 SL600.

What is the the ring gear type?
Is it a 132mm ring gear type (153mm length)?

Or is it 145mm ring gear type (134mm length)?

I know my car has the 2.65 final drive, if that helps at all.

I want to know before I drop a few k on a LSD unit. Thank for any help provided!

There was a group of us that the did a buy from Birds in the UK and we dealt with James Bird - james.bird (a t)birdsauto.com . I would recommend that you reach out to him and ask what he recommends.

The LSD they sell is the Quaife and it works great in the R230. He will also be able to answer the questions you have.
