Looks like 11 and 38 is the ring and pinion gear teeth , so the ratio would be 3.45 to 1 . Not the optimum for fuel economy. The S at the end is probably for LSD, but it easy enough to spin the input and see if the wheels turn in the same direction(good) or in opposite direction (bad)

: I was in the local pick a part and found a 1980 633csi
: 4spd. The diff looked to be clean and in good shape but
: couldn't find an S stamped on the case like I have seen
: other LSDs. The numbers I could find on the case read

: 33 11 1206 183

: and stamped on a metal tab bolted on the cover was

: 11 38A4055 S

: Not sure if that last letter stood for "slip" but would
: love to know if anyone can help (ratio would be good too).

: Thanks, John
