Sorry for the nonsense I replied before.
Should have better read Dan's request before.
LSD (which is the official abbreviation for lysergic acid diethylamine)
or ... limited-slip-differential (guess that's what you mean)
was only available for the 250 and 280ies, but not for the 230ies.
Don't know the numbers they sold.
I guess because it is all on papers when they "recoreded" that back than in the 60ies and 70ies at Daimler,
there is no computer-editable table (Excel) where you can easily extract that kind of info.
Basically (... I am afraid ...) you have to "count" this by reading all the datacards available ....
