I don't THINK so.....but if you want to replace it bad enough and don't want to bother making a patch from scratch.....you can always order a quarter panel and just cut off the section you need!.
the hold panel I think is around $150ish.
and I wouuld think you could resell what was left of the panel for around $80-$100 or more here on fabo to someone that could utilise the lower rear quarter section of the panel or some other section of the panel.
just a thought
