(04-27-2015, 12:21 PM)Duncansport The V8 sub frame is a good swap. The only downside is the super tall ratio in the diff. 

+1 on the V-8 rear subframe swap...theres also the issue of the diff being physically larger and different style mounting to subframe.  I ended up getting a 93+ E320 diff (need V-8 rear cover to mount to subframe though) for closer ratio match but with proper case and correct 6 hole BCD (110mm, I think...I may have swapped that from the 300D rear end).  Either way, definitely NOT the 8 hole BCD flex disc setup from the V-8's.  The rear diff ratio is really close to the 300D and you can grab the speedo from the same car.

Bottom line is that with the larger case, you will need a shorter rear half shaft for the V-8 subframe.  There is likely a bolt on solution using factory parts, but I just went custom.
Just use r129 2.65 diff and r129 500sl half shafts with v8 subframe.
