I've never actually seen those angle bits before, only the door gutter top bit that's on my van.
My van is an HJ Kingswood and mine only has the door gutter top bit that is screwed up. The only thing that is screwed on my pillar is the windscreen stainless.

I did have a ute that had the top door gutter with a stainless strip on it. I took that strip off and put it on mine, it is about an inch short one end, (windscreen).
