Hey, we need a picture of this new idea! What are you using to hold the hinge to the tank? I have been sanding the plastic rim where the hinge will sit and using epoxy. I have yet to pull loose a hinge that is done this way, but not saying it'll be a good fix. I think I only had one maybe 2 hinges come loose off the door. And that is out of 12 conversions. Rivet idea does sound good though!
