Picked up a 87 recently that is believed to be a pro/am.
has these brackets mounted to the rear window at the top. I was thinking it would of been for a set of louvers but no hardware or pictures I come across show these.
Louver brackets. That's what's left of the hinges. Debatable if they're worth holding onto. Someone will probably come across this thread in 15 years and ask if you still have them, because they're the last piece they need to restore their louvers. Otherwise, they're refuse.
