Hello, **Edit. I meant "Hook BOLTS" in the title, but I'm not sure how to edit a title** This weekend I just did a tongue mod where I relocated my second battery a bit farther forward which made room to add a second propane tank next to my first propane tank. The tank mounts with those J-clips; ex. the long metal "bolts" that hook into the tank handle and attach to the tongue of the camper and are secured with wingnuts. I am now in need of a second set of these "brackets" or "bolts" or "J-clips" or whatever they happened to be called. I figured I could stop at home depot or Amazon and get a set, but I'm finding them elusive. Anyone know where to get these? Thanks in advance.
