It makes contact with the bottom of the pinch weld and the inner floor pan. The opening in the lower panel is for a jack with a slotted top to just pick up on the pinch weld. Our ZL1s do not have a jack or any correct info on how to jack the car up. I have the complete manual and the owners manual and they do not give correct info. So I came up with the jack pads so I could lift my car with a lift or floor jack.
