Could this just be another example of poor quality aftermarket panels?

It looks like they could be 'persuaded' to fit.
Have you tried to pull the apron lip over to the bolt hole in the bracket?

Unfortunately most panels now have to be 'modified' in some way to acheive a good fit,although I would have expected yours to be a bit closer than they are.
