Question for Vince that may lead to an answer for Duffey1. Could there be a variation of the B cover that had only a timing hole in a small boss like the A cover but in the B position? I have several early covers that have the lip for the mount all the way across like the cover A-6019-A shown but, these don't have the spot faced bolt holes and the mount boss does not go to the far right bottom hole like the one pictured does. If there could be a variation like this, this could be how Duffey1 is confused. One way to determine this would be the position of the hole in the A cover is close to the second hole from the bottom and the B cover hole would be close to the middle of the second and third hole.
