2003 SL55 Quaife Part number?
I recently purchased a Quaife QDF9V1 thinking it would fit my 03 SL55, but it does not. I took my diff out and disassembled to find I have a 10 bolt ring gear not the 12 bolt on the Quaife. The housing of my diff is cast steel painted black not aluminum as on the E55.
Searching around I see some people suggest the QDF7V for my car. Can anyone verify this would be right for my car? I have a pretty early production 03 (build in 02) with the bolt-on axles. The dealer had a different part number for the diff seals after I gave them my VIN vs what was normally listed for an 03 SL55.
Has anyone else with an 03 installed a Quaife? What part number did you use?

In case any one cares, early (all?) 03 cars like mine have the 210mm rear axle with a 10 bolt ring gear. The correct Quaife part number is QDF7V, which is unfortunately a few hundred $ more than the 9V. I finished the installed and works great! I can't imagine a better mod. If anyone is interested in a DIY I took a bunch of pics along with the install.
One huge short cut of the WIS method if you have the bolt-on axles (again I think some 03's only) is not having to disassemble the rear suspension to slide out the axles. I was able to do the install with my car on four ramps and with no worries of being under a 4300 lb car resting precariously on jackstands.
