Repairing the original frame is an option, but it has to be done right. There are certain procedures and methods involved in repairing a frame that you need to make yourself aware of if you've never tackled a job like this.

That said, I'd go with the YJ frame. It's a better built and more rigid frame. You won't just be repairing(with more failures to probably follow) a stock frame, you will upgrading, and it gives you a chance to more easily address any other issues.
