Thanks Jim. I had assumed the wings were the channels that the pin box bolt to. I was hoping to find the info I needed to be sure the Reese Goose Box would bolt up without having to take off the fiberglass shroud that covers my OEM pin box, confirm, and order the new pinbox. With my work and locations, I just don't want to deal with the hitch uner the trailer, hanging or filling my bed up.
