I watched a program on the Velocity Channel lastnite where they used a chassis from a '26 to convert it into a Brass Era C Cab. It was on the show FantomWorks, based out of Virginia Beach, VA. I heard mention of Model T Haven and Coker Tires in the parts supply as well. They used quarter sawn Oak for the body frame and skinned the sides with sheet metal. The car turned out beautiful....They do most excellent work at that shop. It's worth a look.
