Thanks!
Sorry to take so long for an update. I've decided to continue on a "modular" concept with this build, so the trunk is going to be more-or-less completed first. After painting the entire inside of the trunk it was time to fit the liner to the trunk. This was a two-piece cardboard material that was dropped on top of the metal floor as a protector. Photos show this still in use on the early military Beetles so I fabricated one out of typing paper. After proper fitting it was painted black and glued in place. Also, though it is almost invisible, I've completed the speedometer and switches installation and added the wiring.
