This would be a great sticky post to do going through all the seals on a coupe are a little confusing A list of all the seals and where they fit which members could add to.
I am sure that there would be a lot of discussion on this
I could use some help on the door cover strip seal. I bought a used set of cover strips for my doors, and had then rechromed. I have not removed my existing cover strips, but in looking at this drawing, I am not clear on seals 5, 9, 11 and 12. Which of these usually need to be replaced, or alternatively, should I plan on replacing all of these?
