Hello Lacostas,
986332024
09 is the right part number for a left drive shaft for a 986 EU 03 face lift with 481 option (2.7 228 hp manual 5 speed base boxster).
There is also part number 986332024
51 which is for an 986S EU 03 face lift with M008 / 249 option (3.2 260/266 hp with AT transmission).
So what model year (EU or US), engine and transmission do you have?
Regards, Markus
