1200GS Luggage Mount bolt needed

I'm hoping someone here can help me out. I lost one of those mushroom bolts (and the associated sleeve) for the stock side luggage mounts on a 2011 R1200GS and hoping someone here might have one sitting around that they would be willing to part with. I noticed mine was missing as I was preparing for a ride to ABQ next week, and none of the dealers have them in stock (plus they want a ridiculous price for them even if they did). I was hoping someone had one sitting in their pile of parts when they changed out the stock luggage to something better. Which of course begs the question why I don't have better luggage. To which I will say, I can't afford a new set of Jesse Bags yet :).
I'm in then South/Central Denver area and willing to come pick it up.
Thanks in advance for any help.

Bump. Hoping someone has said mushroom bolt for the stock vario luggage they'd be wiling to sell.

I'm admittedly not familiar with your luggage system, but couldn't you improvise something by taking a trip to a good hardware store?

Might try Bob's BMW in Jessup, Maryland. bobsbmw.com

Tru Value or Ace Hardware? They both carry lots of metric bolts and sleeves.

Thanks all. The problem is this bolt - which is actually called a pin in the BMW parts list - has a very thick (1/2"?) mushroom shaped head that the Vario cases latch on to. Anyone who has a GS that came with the stock luggage racks and then replaced those racks with something better has one laying around. The problem is I just need to find said person :). Thanks for the help though.
