In these pics, it looks like the wheel well totally rusted out, but the dog lets/quarters were fine. I would expect the doglegs and quarters to go with it, which makes me think it may have been repaired before. I'd investigate that, since that would worry me. Who knows if they did it right or screwed it one and put bondo over it, or if they did anything at all. Otherwise it looks to be pretty clean.
