Here's mine, from LMC. Everything said about about the install is true.

If you have to drill the additional hole, as I did, I drilled it through the seat frame support so there's multiple layers and plenty of steel. I'm not an expert like SR above but my instincts tell me the hole I added is as strong or stronger than the factory ones. Hardened washers to avoid pull-through, all of that. I sent photos of the bracing and stuff to another member but can't locate them at the moment.

I don't leave them out like this all the time of course, just for the picture. When not in use they disappear for the most part.
