I feel like a fool asking this but does anyone have a diagram of this, or could describe how they should fit in the trunk? My 94 came with the aluminum wheeled spare but the wing nut for the J-bolt is broken, and the j bolt itself is damaged.. I have new hardware on order. I'm not completely sure how this all goes together. Does the jack open halfway and go under the tire? Where does the tire tool itself go? Just trying to fix little things on the car this winter.
