Ah yeah, those are what they're calling garage storage bags. The differences seem to be largely (if not only) cosmetic. The harness is the part that nobody can seem to get yet. There's a part number, but pricing for it has ranged from $0-$700.They have the door bags for the 2 and 4 door but I don't think they are part of the hard top on board storage system. Just storage bags.
Here are Ford Part #'s I found available on Tasca, as-well-as, most Ford parts sites.
