Gas Tank Leak repair what are my options??

Back in the mid 1970's on my 68 charger I used a piece of rubber fuel line cut down the middle and then put a flat washer on top of that and used a self tapping screw to attach them to the tank. I was a poor kid so I couldn't afford a new tank. I forgot about it until I did a full restore a few years ago and saw the old repair. It mad me laugh remembering the things you do when you are poor, but It was still holding as good as ever over 40 years later. With that said replacing the tank is the right way to do it and I did just that during my restoration.
