Xjr wheels on 1996 xj6

Hi guys, in new here and need some advice please.

I have just purchased a very well kept 96 xj6 3.2.
Being a traditional kind of guy I have also purchased a set of xjr6 alloys also from an x300.

Can anyone tell me if the wheel nuts that currently hold the dimple alloys on will also hold the xjr6 alloys on? I have the car booked in to have the wheels swopped over at my local garage on Saturday when I go and buy the car .

I do not know if the xj6 has long or short nuts as I don’t have the car yet.

Any help gratefully appreciated as I don’t want to waste my chaps time at the garage, also my current wife has lots of hyacinth bucket style stuff planned for the afternoon so I’m trying to avoid annoying her, another car is enough!!

“DOOOOOO come along Richard!!”
