The tray sits on TOP of the spare to hold the jack etc.

If you already have the car and "spare" (stud) I'd think all you need to do is just see if it fits in the recess in the trunk.

I feel much better now I have the (donut) spare wheel from the dealer (the tray comes with it). Also had to get the rubber tire as a seperate item as well - Total of about $200 which is rather a lot for something that should have come with the car - the gunk won't help in the case of a tire shreaded by a pothole, which is what happened to me last time I needed a spare
