[BGP2018]

I have been looking at the wheel arch for my 2018 forester, however for some reason the factoey model was designed with a very unsightly gap on the rear facing side of about 10cm. Since my car is white, it stands out. I have no interest in such a poorly designed product, but despite my best efforts i am unable to find arch covers that are contiguous. Can anyone point me to a good part for this?
