I have been told that there is a a Ford upper wish bone that will fit on a 2004 XJR but the independence repair facility would not give up the part number. Does any one know what it is?

 

6W4Z3084AA RHS don't know about LHS can't find one .

id say more research is required here .because although this looks correct ,
jaguar did modify them from 2002.5 .
and there are three different variants from ford as well ,
i think it would be wise to get the jaguar part. or a trusted aftermarket brand that states its for your model .

these would be a bargain if they were any good , but made in taiwan i would not trust them ,

this i might trust a little more .
