Cheers Tony. I was thinking I was going to have to fit one as I can't see another way of making it look neat and tidy.
Yes I think it would be difficult.
On the carpets where they fit over the front wheel arch. I secured them at the top on the A post using a self tapper but I found the have a tendency to not fit snugly onto the wheel arch itself, they sort of flop forwards a bit and leave a gap, so I used some double sided tape to make them sit flush against the top of the wheel arch.
