XJRs: which 18" wheels are which?

[BT52]

There are the star shaped ones (5 thick spokes) and the later 7 spoke ones.

Anyone know the names of these wheels and whether they are interchangable on a '98 XJR?

And does anyone knows of any 7-spokes for sale (people who have changed to 19" perhaps?)

There are a number of 18" wheels available. I have "Double Fives" 18" as fitted as standard on the XKR. They are interchangable with the old XJ8/R using the same 120.5 x 5 PCD. This different to the new XJ, X and S Type
