Louvers were a 71 only thing, 70s had a whole different body line. And from what I've been told only black and white cars got black louvers. I've seen a orange car with orange louvers, so the black trim would stick out like a sore thumb. It would be nice to know when the holes were added to the roof and 1/4 panel, were they drilled after the fact or stamped during the panel mfg. process.We found evidence that my car was taken off the line and had some more paint work done, but don't know what or why.
