You should know the amber lense is the same on both sides, but the buckets are corner specific.
Original buckets are marked to indicate the side and front or rear location with two letters :
Italian-
front=Anteriore
Rear=Posteriore
Right=Destra
Left=Sinistra
Example = AS = front left
The buckets are designed so the lens sits parallel with the center of the car, and because the curvature of front and rear fenders varies from corner to corner each bucket is different.
I know of one vendor who reproduced the buckets but only made two types and he told me that there were only two types from the factory. He is wrong.
Now, kitty corner buckets will interchange, they are close matches, but they are not the same and will not hold the lenses parallel to the centerline. Not that anyone would ever notice.
My 2¢ of trivia 😉
