Dont know of ready to fit ones made for mustangs , but i do know that XK-XP falcon towbars will bolt up as they are the same as the 66 rail spacing , i have about 3 towbars here on wrecks and have measured up. However you will have to bring the tow ball tounge down under the valance and up again , or cut a slice immediately below the number plate for the tounge to slide in. I was thinking of making a reece hitch type for mine with a square chrome trim in the valance so it can be removed.
