3 locations I've ever seen them located. The jack in the corner (as mentioned), and
under the seat, as well as behind the seat. They had sort of a pouch/pocketed thing
draped behind the seat that carried crank jack, and tire iron. They also had a spring that
stretched over a crank, or hydraulic jack under the seat, and a couple of metal straps
to secure the lug wrench.
