My wife and I did Rt 66 from Chicago to LA last August with Eagle Rider Tours. The tour guide who's name is River Pilot led the tour as an employee of Eagle Rider. He has since left the company and now offers a complete GPS map of Rt 66. Attached is his contact information. Hope this helps. River is very knowledge of your intended ride and can give you some very good information. Say hello for me when you talk to him.

Thanks for that, i'll send of an email soon. If nothing else comes of it, his website shows a great ride itinerary. Though 17 days is a tad long.
