The jack is screwed onto the car, with the spare wheel over it. I've not had anything to hold the wheel in place, and the brace has to be put loose underneath it too, as I can't see any other decent place for it to go. I recently bought two second hand brackets to hold the wheel down, because one was too short, the other was too long! So, at last I'm asking, anyone who has one of these - how is it all meant to be held in there? The loose brace even makes me wonder if there should be a foam holder or something. Thanks for any info
