I know my 85' 300D doesn't have a limited, but I am wondering if anyone knows a way, or if it's even possible, to get and install an new differential or gearset that will my make it a limited. I don't care if it's OE OEM or aftermarket, but obviousely would prefer an OE/OEM option. I'm pretty sure limiteds were options on 86'+ w126 models and would really like the added traction for the comming winters; as it is hilly in PA no matter how good of a driver you are.

I don't think any 126 came with a limited slip differential. I believe ASR or whatever that snowflake button engages uses the ABS system to effect traction control.

Check out www.quaife.co.uk. Better than any mechanical LSD.

I know a 560SEL has a LSD.

The 560 SEL was the only 126 in the 86+ cars to have a limited slip diff. Maybe the 500SEL has it???? Does anyone know?

The W123 chasssis uses a 185MM ring gear, & the W126 chassis car uses a 210MM ring gear so this swap can't happen. The only US car with limited slip & 185 MM ring gear was the 190E 2.3 16V. When I was autocrossing a 1981 280E(W123) I installed a 3.69(240D)with the 16V limited slip(carrier) & boy was that an improvement. Took a bit of work as it isn't a bolt-in job.
Had to have ring gear spacer made to use the limited slip carrier into the W123 case. NOT a diyer!!!
