Spare tire hold-down
If you go to your local hardware store and get a carriage bolt and big wing nut you will have something very close to the factory setup.
The wing nut tightens against the jack base.
This would be the $2.00 option. The factory wing nut (as shown below is a little different).
If you want to go all out you will need the board, cup and another wing nut.
