I am in the process of completing the restoration of my 911, 1966. I am wondering if I do need the upper door seals on the doors, part nr 91154240301 and 40401. I do know that I absolutely need the big door seals between the door and the body. But do I need the upper door seals too? They seem to be original parts, stoddard list them but they seem to be optional.

Tks for answering me
