I'll put up a figure to get the debate started: for just one side: $50 plus postage.  I support light grey- easier to cover with a couple of spray coats than white.
For whatever reason, it seems most people lose the right side one.  I still can't fathom how mine was lost, and I blame theft.  The replacement is held in with a short bolt and nut.  If you want to test your dexterity and patience, try getting that nut on!

Long-time rider & stalker here... I'm actually pencilling this one in  . I'll be on something German, so will park at the end - out of view  .

Just noticed the  in Shillas's post.  There must be something about Karoonda sausage rolls that I don't know about.
