Already replaced the rim - went the whole hog and got a new one from Germany! I was like a kid at Christmas opening his big present when it turned up!!!That's very light damage, but strange that the LHR wheel is damaged and the RHR wing. As long as the suspension isn't damaged, it should be back on the road in no time.
The wing will be easy to source. I think all wide-bodies use the same rear wings.
It might be easier to get a whole new set of rims than trying to find a single rear, but you don't know what's out there until you look.
Have fun.
