My 50 panel had one peice of plywood with the metal strips over it, not seperate planks like a p/u. I believe the plywood was cut to shape and installed during the building of the body. Why I say this is because I couldn't get it out in one peice. I was replacing the wood anyway so i cut it in half from frt to rear and removed it in two pieces. To replace it I needed two sheets of oak plywood i made a ship lap joint in the middle. Using the old wood as a templet I lined it up so the joint would be under the center medal strip. Then install the side with the lower half of the ship lap joint. Install the other side and Gorrila glue the joint. Done! ps. I sealed all the plywood with fiber glass resin before I installed it. Not an easy job, but it can be done. Not to break your stones, I would also install a heat shield. Hope this helps, Good Luck.
