There is also something called overnight shipping. Call Pat Walsh,Twisted Throttle or Amotostuff, they are masters at dealing with last minute issues.
I bought my bike on a Saturday, Decided on Monday to do a loop of the Trans Lab highway and left Thursday Morning. I was kind of in the same boat.
I started with basically a stock bike and left with crash bars, top box, accessory plug .. etc.
You may be able to get something that Parts Unlimited carries (a.k.a. Dennis Kirk) from your dealer the next day. I got a set of TKC's for my TL trip that way. Of course I paid full retail price for them.
