I was wondering the same, as im putting together a 69Z and I actually am planning to use nos door weatherstrips - but was going to go aftermarket on the roofrails.....maybe the latex. So im very interested in the opinion on this.

My thought
process was the doors with the nos weatherstrips would have the most impact on the closing capability/easeness. The roof rails, not so much as there is a lot to do with window alignment, tightness at the top etc that affect the ability close easily which I felt that I can adjust the windows to the roof rail to manage the closure. I cannot affect the doors at all with hard weatherstrip. Just my opinion, would look to others for their POV.
