Mr Si

Hi I had the unfortunate event of a puncture last night on the M1. As no spare in boot, tried to use the air pump and gunk thing, but did nothing as puncture too big. Had to get the car recovered. Ive been looking today for a spacesaver, and the ones ive seen say xf 2003 to present day. Are all the fittings the same? Some say for jag xe, xf, xj i can see they are all 5 stud. Thanks
