I see that Goodmark now has full quarters for
66-67 Chevelles, If someone has seen and or
installed one please give your opinion on the
quality.

Hi Soybean, I'm waiting on the same thing myself, they're not available to me locally until sometime here in March. Paddocks in Knightstown is supposed to carry them. To answer your question, I've been keeping an eye out for feedback on them for a couple a weeks, and there was some conversation posted here about a week or 2 ago. They were saying that they're pretty good quality, and fit like a glove. That's probably the one I go with. Good luck!
