That's a tuff find, I doubt if anyone repros SW woodgrain, NOS is probally your only choice if you want a match, if your just looking for woodgrain (automotive grade) and want to make your own decals, Trim-Brite (makers of auto decals/trim/moldings) carries a sheet of heavy vinyl woodgrain, very dark in color, and very nice looking, very realistic grain and texture, the sheet/roll is 24" wide by 25 feet long, it is sold as station wagon woodgrain, I generally use it for redoing dashes and consoles, door panels in Mopar restorations, as it matches the grain and color very nicely,....if interested I could send you a sample to see if it's what you want?,..just PM me your shipping address, I'll send you a sample....a 24"X25 foot roll is approx $75 available thru your local auto parts store that carries Trim-Brite products, or believe it or not JC Whitney. & CO.
