2018-2024 Lincoln Navigator Core support. Part number LL7Z-16138-A. Genuine Ford part. Currently on national backorder from the supplier but we have just this one in stock. This is a difficult item to ship and we would prefer pick up at our Odenville, Alabama store. If you are too far away and need it shipped then please contact us as our online cart system will not have an accurate cost. This will likely be a truck freight item due to it's size.
