Lincoln sells a roof rack for the LS. It is a Yakima rack with Lincoln logos on it. Unfortunately, it is somewhat difficult to install. Each of the four clips bolts onto the roof under the weatherstripping with nutserts. You have to pull back the weatherstripping, drill 4 holes per side and install the nutserts. After that, you can install and remove the rack by bolting and unbolting. Since it is a Yakima rack, it works with all Yakima mounts, accessories, etc.
