I thi k 67s are different. You have a small square hole in between the loops. That's where the insulators hook up.

Here ya go Ulf. These are 1967 covers. @CudaChick1968 had these pictured on her site. I see the holes for the spark plug wire insulators. If you look carefully, you can see the slot on the right side of the top valve cover on post#1 (last photo)
