JD gave you the correct link address. On mine I took some rubber backed carpet squares and turned the carpet side down rubber side up. I 3M glued them down and then wire tied then to the holes in the jacking pads and they work great much better than the OEM pads. My handle broke off at the jack and had to weld that back on too.
The pads on mine are still good except all the nipples are broken off.
My plan was to buy new pads and glue them on. I still may do that to the old pads. Clean them up and throw some Gorilla glue down
