Hi,I've got a 2005 gs(not adventure),I'm looking at changing the plastic tank cover and beak to a different colour but want to keep the originals,I've been offered a pair for sale from a 2006 model,I asked him if they were from a 1200gs or adventure model,he replied they're all the same,before I go ahead could someone confirm if they're both the same or can they be made fit or any difference?
