Yes, an old topic, but more data for the same subject. Look at 5 different unrestored 67's over the past month, and 4 coupes (R, F, and T mix) are all the "C" type for trunk lid weatherstrip. The one fastback 7F02C165... was the trapezoid shape. I've included a pic. The second pic is one of the coupes 7T01C144... showing the "C" shape.
