I bought a used cargo trailer and PO had installed (2) removable motorcycle chocks. However he wouldn’t sell them as he uses them in his new trailer. I have stopped at trailer store and looked on line. Seems to be about 10 years old so they don’t make this version any more. I can always get new ones and remount but before I went that route I figured I would see if any of the brethren had two they wanted to part with. They are the type that have 4 Phillip head screw that you screw it down with. They are spaced 6 3/4” north and south and 5 1/2” east to East to west. Can always email or text a pic to confirm.
Thank you kindly. Mattyd
