There are 67-68 full factory style quarters for coupes that have been manufactured with new tooling and that have just arrived (within the last month) at the parts houses. Convertible versions are expected within two months, hopefully sooner than later.
The '69s have been available for a while and I have seen generally positive comments about them. There was, I have read, a short run of some '67-68 full quarters released a year or more ago that were of poor quality.
The skins and 80% quarters have also been released in good and bad batches. The chevrons were incorrect on some early ones and the lower front reveal line above the rocker was off by a 1/4" or so on some of these.
The full '67-68 Camaro repro quarters had problems with the distance between the deck lid gap and top fender line being off by 1/2" or so (pretty major error for a dimension that is about 3").
I just don't see any options for some of us as used and NOS are both extremely rare. Hence, I'm anxious to see the repros.
I hope this is specific enough for you. So are the quarters you are referring to the same ones that were just released (i.e., within the last month)?
