I don't know which one you should get, but I would recommend AGAINST the two round red ones in your search list (or the black equivalents).
I tried a Prothane brand polyurethane pad, but the material is too slippery for that use. The car would have slid off the jack if I had tried to jack it up enough. I guess the material might be fine in a pinch weld application, where it can't slip.
