Here's a link with pictures should you want to make your own comparisons.

Fins do not = LSD I " think " MB last used LSD on a 80's era 190 E W201 Sport line or some other racing spec option. There is a hydraulic limited slip diff in the 80's as well ( early 4matic wagons ? ) , it has a 3/16" ish steel line running to each side of the diff.

The R129 never came with LSD, it used ASR ( Acceleration Slip Regulation ) . Also, there were many different diff sizes and axle lengths in the R129 so be sure to do some research to see what you have right now before looking to replace it.
