Slant 6 lift points

No problem with not pulling the trans... that is my general preference.

And yes they will hold.... use grade 5 bolts or better. I suspect the factory process would be to use both bolts to mount a plate with a hole in it for a hook. But, I am kinda like you..... that seems pretty lightweight, and so I used a second safety chain loosely around the manifolds as a back up.
