no affiliation, I just spotted this on ebay
http://www.ebay.com/itm/Quaife-ATB-differential-QDF28B-for-Mercedes-W208-W203-W210-W209-/291522209933?hash=item43e013e88d
buy it now is less than half the regular cost (normal cost is approx $1400)

this diff is for 2003 sl55s and 2003 e55s (up to some chassis number that escapes me at the moment). it is for the cars that came with the 210 axle 10 bolt ring gear.

I just paid 1100 or so for mine in the group buy a few months ago and love it.

Cheers,
Chris

Qdf7v is also a 10 bolt,with bolt on axels, that's what I put in my 03 SL55 ,check your application,qdf7v unit is around 1400 ,I believe they split that year so make sure before you grab that one .

Qdf7v is the old part number .... The current part number for your application and all 2003 10-bolt 210 axle cars is QDF28b.

I just looked it up in the EPC and according to MBZ, this DIFF is for all SL55s through build number 069434 (last 6 digits of your VIN). THis is the same part number DIFF (QDF28b) that I put in my 2003 SL55 (build # 040469) a few months ago. This WILL fit your SL55 (and E55) if you have bolt on axles and your DIFF case number is "A230 351 01 05" See pic of the number on my case below.

$695 for a brand new in the box quaife is a GREAT price (again, not affiliated with seller).
