I've got a bag of fabric pop rivets, for some
odd reason.  They come in handy for engine

It's an early champion citabria. Has oleo landing gear like a champ. Fabric is held on with screws but I have read somewhere that they can be replaced with rivets.

In that case , I would advise converting to rivets
You will find that the screw holes will be oversized in some cases . Using rivets will eliminate the need to upsize some screws and they are also easier to install
Plus rivets have a lower profile on the rib
