Did I buy the wrong thing?

Bought a brand new fourtrax 300 centrifugal clutch on ebay and it says its only for the 2×4 models and the seller has another one that looks the same and says its only for 4×4 models.. although I checked bike bandit and all the "part numbers" are the same?? so its fine?? I’m sure some of you know if its compatible with both types of driveshafts.
