Securing spare wheel
Having bought a spare wheel I need to fix it in the boot. Have bought foam surround and the spare wheel retainer from Vx. part no 20964981 which consists of a bolt with a large platic head shaped to presumably fit inside the spare wheel. With it came a dished metal plate through which the threaded bolt can pass.
My question is how does this fix the wheel to the car, is there a nut as part of the boot floor fitted to all Antaras, wether or not they came from the factory with the inflation kit.
Antara is a 2015 SE x4 manual.
Many thanks in advance,
