From memory, that is correct. I did all 3 cars at the same time so can't recall which one was mounted in what way. But if you take the wheel off, you should be able to see all the screws that hold it on. I think there might be some on the arch itself too, or maybe that was the other cars???? Damn.
Good idea to give them a good clean and behind them while you have them off, you cannot believe the amount of gunk that builds up behind them.
