3M was the main manufacturer of the automotive woodgrain vinyl "decal". Rolls of that stuff are still around, but in only a few grains/colors. From what I found out about a year ago, everyone that has anything sells the same stuff. Check the automotive 3M website, possibly. Seems like I found that stuff from a Google search of "woodgrain automotive", if I recall correctly. Most of the darker grain that was used is a close match to what was on the Chrysler minivans.
