I had this happen on an old car changing a tire when all the cars came with these types of jacks in them LOL. Sorry to hear that about the 4xG sliders that's a lot of money spent to have them not work as advertised The SA sliders stick out a lot further then the 4xG so if you had a strap or a chain you could wrap around the tubed part you could lift there I guess. I won't be getting a that type of jack though I'd rather put my floor jack in the back of the XK instead LOL
