Here take a look at this pic:
You'll notice the Sapph dash (actually a late Merkur - same thing) installed on my 3 door. Notice the gaps at the ends where the A-pillars join. That's why you need to also get the early Sapph A-pillar trims which fill in these gaps. One thing to note is that the screwholes in the Mark 2 A-trim don't match, so you'll need to drill new ones or better yet, use double stick tape and place them in place.
