The smaller tools were stored in a canvase bag and all the collection was essentially loose behind the seat. Rattle, shake, cling, clang, thump and more rattle .... oh what fun!
Don't forget about the hand crank too. Im not sure if the jack would fix behind the seat, the one I got is much too bulky, its a bottle style with a T handle on top that doubles as a hub cap remover tool and a lug wrench too
