When I was researching for my seat project last summer I stumbled across someone's project AD truck that did the plywood/foam seat. It was an excellent and long blog type project history post, plenty of photos and information. HOWEVER...just how I'm unable to find it.
If memory serves, the project was from a few years ago. Hopefully someone can provide a link cause it is a great project how-to piece.
Good Luck,
Ron
