I think the arms are mounted the same and are the same length on our Magna. I did have to move them to get the mirrors adjusted right and then the cameras aren't where I'd like them. On the top side of the arm by the mount there should be a removable "plug", under it is a bolt that you can loosen to move the arm. On the bottom of the arm out under the mirror should be an allen type bolt. Might take some work to get that one freed up. I had to loosen it slightly and hit the wrench with a hammer lightly and repeat several times to get them loose.
Thank you, Mr_D and Smitty!
Actually, the arms are the same, but the way they are mounted are different. The one on the passenger side sets about 8" out and extends about 16" from the coach to the front while the one drive side sets about 18" out and about 6" shorter than the front of the coach. These pics may help
