Oh, I was thinking of putting the hub disk on the back side of the mount so that it mates with the spare as it does in stock form. It would be hidden that way tho. I think having just a bent plate or 2 welded flat pieces would vibrate really badly without some sort of gusseting or bracing. I saw that the AC is 10.25 lbs and the 1/8" plate could hold that no problem but I think without any bracing between the two faces it will vibrate too much. Just my thoughts. It would be cool to integrate a hose storage method into the bracket so the hose could circle the AC along the inner circumference of the rim also!
