Maybe Mike(?) at Roseville can chime in on the Goodmark e-body Cuda quarter issues also? They appear to be a volume seller and they recently showed pics of a 71 cuda they resto'd with new quarters hung. Maybe they have a large pool of experience to quote from. This really sounds disappointing after the long wait.

The gist from the above discussion is that the full quarters are only minimally better than the patch panels that everyone has been butt welding in while saving the perimeter from the original.
