Jeep catalytic converter question (easy for someone who's been there before)

My friend's 1993 Jeep Wrangler's cat is starting to rattle. Looking online, it looks like the converter is just secured with a muffler clamp at each end. That's it? No gasket? Anything else involved? It's a 4.0L 4x4 with a manual gearbox--all stock. And I'm assuming that a skinny person can shimmy underneath and do it, right?

Thanks.

i dont remember if the cat is under the center skid plate or not. This is what the direct replacement magnaflow looks like. Here is a video of someone doing it on a 93 https://www.youtube.com/watch?v=TUZi_az0-sY

It looks like it is welded to the muffler.
