I am not sure about a 67' 68-69 had a specific style that differs from earlier or later. The construction of mine was medium density foam molded over a metal frame and covered with vinyl. The vinyl covering uses a thermal vacuum process which I avoided by using stitching for the curvy areas. The wood is just a veneer.
The step nose dashes may use a similar construction but I think the wood is a special type of vinyl. I'm sure there are other posts here covering it in detail.
