Has anybody used rivet nuts to install sidekick

I live in Venezuela and i cant find well nuts anywhere, im seeking solutions and i found rivet nuts but im kinda on the fence about them, im wondering if anybody has any experience with them.

Im worried about plastic not being strong enough for the rivet to retract over it and making a bigger hole

I used wellnuts and rivets to install my anchor trolley last year on my 2014 Hobie Sport. Both wellnuts and rivets were suggested to me on this forum. Where I could, I used the wellnuts, but there were a couple of places I couldn't reach inside, so I bought a rivet gun. Very easy and strong application.

I installed an anchor trolley on my 2014 Hobie Sport using wellnuts and rivets. Wellnuts worked well, and I used a rivet gun for the tricky spots. Easy and secure!
