May want to look for a better cab to start with. Unless you are planning a 100 point resto, most of the floor can be hand formed. Weld in the custom pieces that are available and make the rest. Our 60-66 trucks aren't the hot item on the aftermarket scene yet but it's getting better.
Good luck,
Scott
