Oye the guy at Autozone is just a parts guy, not a tech. To some of them mechanics is Gandalf level wizardry. You are overthinking the problem. Relax, take a deep breath. That positive terminal is nothing special. It has no fusible links on it and it just has two terminals bolted to it. Easy peasy. Just look for something like https://www.12voltplanet.co.uk/positive-battery-terminal-clamp-3-stud-connection.html <-- That. You may have to break som plastic to split the termials up or to align them .. But you don't need a Hyundai part. For the negative side, same thing but you only need one post .. Like https://www.amazon.com/91980-3X010-Positive-Battery-Terminals-Connection/dp/B0B469N15F that -- These things exist, they are cheap .. And EASY fixes. You got this.
