73 Dart rear quarter redesign ideas?

Good to see my car isn't the only one with the quarter cut out like that. I didn't decide to do it like that, the quarters were all rusted out and when we started work on them we founds loads of bondo. We later figured out that the previous owner cut them out then just bended the flat metal up to make a flange which caved in the rest of the quarter. It a while to fix it but this time we got it done right and I think it looks better than it did stock(not to offend any other die hard Dart lovers).
