Rear arms

[B.different]

Hi all, Could anyone be able to tell me the difference between the rear arms 7E0501414A 7E0501413A and 7HO501071 7H0501072 mine. Thought all the backend suspension was the same? Any help much appreciated

I wonder if the 4 motion rear arms are different to allow space for the drive shafts etc.
Just a thought, without actually answering the question!

Never thought of that
