The chrome trim goes all around the windshield, there are 1"-wide trim pieces (1 each for top and 1 for bottom) that goes along the bottom and the top of the windshield, chrome metal piece.
Yep, That is different. It makes a very nice windshield look. Much better than my '67. I have a friend who found a trim moulding and installed it on his '69. It looks factory and looks great. I need to get a picture and post it. Good luck with your '66! Stan
