I am not an expert but it looks like you got them. I have been using a lift for over 50 years starting out pumping gas and changing
oil since the early '70s when gas stations provided service. I was told to "catch the frame" and as long as the car starts lifting the car eveningly, all is good. Has not failed me yet when using lifts today at friends that are fortunate to have a garage with a ceiling tall enough for a lift.
