jack stands
Sorry, I don't like the looks of ANY of those plastic things. Years ago, when I was stuck with ramps, I welded fore/aft support angles under mine with sheet metal for more surface on "ground."
So far as the pins, I bet the shear strength of a GRADE 2 bolt is more more MORE than way strong enough. You are looking at TWO shear point's per jackstand, that makes 8 for the weight of the car
