centro 4.1 rear arms

[Chunkton]

Hi, This maybe a silly question but, i am converting a b4 into a centro, had all the fun with gearbox ect, just about to fit the rear suspension arms, I understand the left and right arms are fitted on the other sides due to shocks fitting on the back, Do you have to swap the hubs over or fit them on their intended sides??
Thanks in advance for assistance.
