I went to Ace and got a 1" coupler nut, 2" threaded rod, and a regular nut. The tire actually fits down into the spare well about halfway. The J hook comes up through the center of the rim and then I use a large plate washer and the regular nut to hold it down. Then I add the coupler nut and rod and the jack then goes down and I use another plate washer and the original wing nut that came with the car. After I lay the carpet floor piece down over it all, the floor is raised about half the width of the tire. The side pieces of the floor carpet are wide enough that they just lay down on the sides and I basically just have a raised floor in the trunk but have ample room to put things in there if I want or need to. This arrangement will suffice for my needs. I guess everyone else who wants something will just have to figure out how they want to do it. I can rest easy that I have a full sized tire on a factory rim whenever I need to change a tire to get home. I know others will have other ideas. Just thought I would pass this on as a possibility. My best to all. L.M.
