Hi all, We will be getting a 1998 Expedition, Eddie Bauer edition from a family member that has about 140K miles and looks and runs like new. They ordered it new and did not opt for the 3rd row seat. We will need the 3rd row and am looking for information on what is needed to install it. What parts will be needed and possibly where is the best place to get them on the used market. I've been searching places like You Tube but no luck in this vintage. Thanks in advance!
