A set of Jimmy 9 wheels from Wheelkid (Jimmy at www.rallyamerica.com) here on the HAMB with woodgrained or hydrographic dipped spokes would give you a safe steel wheel with the look of wood spokes....
There is a whole lot of wood in the body of a '29 Nash. I have a sedan that was my fathers. make sure it's not 'rotted' to death... nice score tho
