Jaredwhat I was thinking is if you can get the key to sort of fit in the axle and then wrap it with the strip of coke can, somehow hold it tight and then with a cold chisel tap on each side of the key and you might be able to square it up enough to hold the key in place while you get the wheel back onto the axle. Then you need to make sure that you can get the wheel tightened up nice and tight so that it can't move at all. Any movement will cause it to quickly chew the coke shim out
