I still have the arms. I just need to be able to spread them a bit wider for some of my equipment, and the tires get in the way. The tires are already reversed as one person suggested, so the best solution is to offset the arm. I really don't need but about an inch on each side, for a total of 2". The offset arms I tried, but were much too short, had an offset of about 4 inches per side. I can't really imagine anyone needing that much offset.
