1985 USA 308 QV Rear Bumper rubber cover plates

Hello all. Apologies if this has been covered, but I can't find it....

I am "restoring" the left and right hand rear rubber bumper covers. I've attached a photo for reference (not my cover - stolen from the internet!). They have obviously been removed before and when replaced a combination of rivets and screws have been used. Can someone please advise what the factory used?

I believe the factory used rivets

 

Thanks Mike - what is the belief based on?

 

My car and others that I’ve seen and well known for a f@ct that it is original.

 

I have an 85 euro and one side was coming loose and they were riveted on

 

Rivets were used for my ‘85 QV, I “fixed” on that was sagging with a small screw and nut after a river had broken.
