So far, many of the e-body PGCLassics stuff seems to fit good; just not always look right like the rallye dash woodgrain.
When it comes to sheetmetal, I hear the only thing that fits really good are the Goodmark R/T hoods. The Chally full quarters are okay, but not perfect.
Front and rear valences are way off from what I understand. Rears the worse of the two.
Before diving into repro parts, do your research and wait for others to be the guinea pigs.
