WTB: Cigarette adapter cord for 72W AC/DC

[Habakkuk]

Ok, my story is this: I purchased IBM 72W AC/DC adapter to use it on the road. However, it came to me only with the regular home plug. It did not include the 12V one. The seller doesn't want to do anything about it. His excuse is that I had to ask and he specifically posted it in the ad. Oh well, live and learn I guess.

At this point I basically have a 72W AC adapter with the option of "DC upgrade". Is there anyone out there willing to sell me the 12V cord from a deceased AC/DC brick? I know it is a long shot but I figured I'd ask and maybe the impossible will happen.
