I redone the wood in my 64 with standard lumber yard wood. all you need is a router and table and a rabbiting bit. I bought new strips and galvanized carrage bolts and started in the middle and worked my way out one board at a time. My truck was just a driver so I sprayed it down with clear deck sealer when I was done.
Question; On my 64, the old wood was pine. On my 63 I beleive the wood was original and it was oak. The question being, was the kind of wood a factory option or did they just use whatever was supplied to them at the time?
