Limited Slip Differential on datacard code

From 2013-2016 I owned a 2013 c63 with P31 and LSD. I loved it so much that I now want to buy one again in that same configuration (with p31 as well as LSD). I have gone through quite a few listings, and I have noticed on data cards posted, some data cards say: "471: limited slip differential" and others show: "471: locking differential". Are both of these wordings referring to the same OEM Limited Slip Differential option? I am just a little skeptical/confused because I know that technically a locking diff is different from a full LSD, but the option code for LSD was 471 (if I remember correctly).
Further, on these data cards, it states "p30: AMG performance package". I thought the option code was p31? Can someone please help clarify this for me as well.
I really appreciate it.
Thanks!




P30 is the option code on the data card, the option was called P31 on the newer cars, but the data card always shows P30 for all years (or P61 for a 507 car)

Anyway, the way to confirm that it is a P31 is to look for option codes P30, option code 923 "OUTPUT INCREASE OF ENGINES" and option code 251 "INCREASED SPEED LIMIT FOR NAFTA"
