How about some part numbers folks !!
OK - UK Spec cars is...
Drivers Side ( Offside )
R82 00 427 869 00K02 Bush Rubber £41.42
Passenger Side ( Nearside )
R82 00 427 868 Bush Rubber @ £41.42
This is standard retail price - trade discount would be greater. Note that these may take a couple of days to order in although this is perhaps a common high wearing part.
Hope this helps
