My 1995 Non ASR C36 has the same 185mm 3.07 diff as well. It looks like a W124 style diff versus the updated W202 style. I don't believe it is LSD as there are no markings on the diff to indicate that at all.
hello @ccrelan. how did you get 3.07 rear on your 1995 4 speed 722.3 c36? stock is 2.87.
hows is in highways cruising at 70 mph or 110 kph?
thanks
