Difference between these two parts?

[Antharro]

Car is a 2002 Camry MCV30R (1MZ-FE / XLE).

I'm trying to find out what the physical difference is between these two parts. All I can find out, and all my local dealer can tell me, is that one is for North American built cars, whereas the other is for Japanese built cars.

53801-AA020 (also listed as -33120 and -33110) - dealer tells me this is the NA LHD car OSF / passenger front wing.

53801-33100 (also listed as -33140) - dealer tells me this is the Japanese RHD car OSF / driver front wing.

Does anyone know if there is a physical difference between them, or if the different part numbers are simply used to differentiate between Japanese and North American cars and supply chains?

Thanks!
