Rivet size for Terraplane canopy hinge?

[Heavy Armor]

I have never in my life worked with rivets, so I'm completely unfamiliar with them. I bought a gun and a pack of what I thought were the correct size for the canopy hinge, but realized after the 1st attempt that they're much too short. For fear of busting my fiberglass, can someone maybe tell me what size rivets I NEED to be looking for? Thanks!

I believe that are 1/8 with a 1/4 inch reach. Keep in mind that you will need washers to go on the back ( fiberglass side ).

Buy an assortment of lengths.
