Rotor Suggestions (I'm sure I am overthinking this)

I would stay OEM the new metal sucks. Have the rotors resurfaced.
This is what led me to my overthinking! I'm sure these rotors have been turned before is there a minimum thickness they need to be? That's what I'm currently researching lol. I do know the calipers are gone there's no getting around that there so rusty and gross I'm just not comfortable with them.
