Twelve South Back Pack & new iMac

[BlueEagle]

Just curious if anyone out there has figured out a way to attach their twelve south back to the new 24in iMac? It was originally on a 27 inch iMac. I tried installing the backpack on the new iMac but the plastic adaptor inserts that go into the clamps are to wide making the backpack just wants to slide down the stand of the iMac. also the old iMacs had an angled stand where the new one is straight up and down. I know its long shot but figured I would ask here for ideas. Thanks guys.
