In currently almost finished with my swap. I ditched the gear box and swapped a rack and pinion from a w210 in, I was going to run a T56, which fits without modifying the trans tunnel, but switched directions since the 4L60E has a shorter first gear which will work better with the 2.65 rear gear im running. that's the only option for a factory lsd (450 sel 6.9 rear diff)
do you have pictures of how you adapted the rack and pinion? i would be super interested!
how much space did you save? if this is a valid option, it might be a good way to go instead of the crazy routing of the exhaust on my v12 s123 build, lacks space for the downpipe from the turbo on the driveside, so need route that behind the engine and join the passengerside downpipe
(yes i do have space for that routing, yes it is darn f-ing tight)
a rack and pinion would be better if/when i decide to make it somewhat driftable to.

btw, the w126 and the r107 and w116 also had LSD as an extra,
3.06 and 3.07 large house from 450se/sl/slc,
3.27 in the 380SE/SEC
2.47 in the 380SE/SEC and 2.24 in the 500SE...
have both 3.27 and 2.47 and the 2.65, but am looking for the 3.07 in a LSD version, gearratio wise, the 2.47 was a little to though on the gearbox with dieseltorque
althou those are superrare in the us, but know of people that has imported the 3.07 from Canada here to Sweden.
they might not be as hard to find as the elusive 6.9 differential, but im not shure.
