Before I change the rear window?

Picked up a GREAT rear window from Steve's Muscle Cars in ARK Saturday, mine had scratches on the back that could not be removed. (Going to keep it for a spare).

1. Before I remove the rear glass I noticed there are some plastic "trim" in between the rear window gaskets and the headliner. Of course they are brittle...... Do they make some replacements or what id everyone using to hide the end of the headliners.

2. Should I go with a "chrome" locking strip or black? What is stock?

3. Speaking of brittle, do they make the rear curved plastic trim that hides the holes for the chrome rear window trim? I know there are plugs for the center but trying to find the other side covers......
