This is the 12th in a series of posts on the Porsche restoration of this 1964 Porsche 356C. Part One of Porsche Restoration described condition of the Porsche after media blasting and the rebuild of the B-post, Part Two of Porsche Restoration explains the fender reconstruction process, Part Three of Porsche Restoration covered the front end reconstruction, Part Four of Porsche Restoration described the rebuild of the right-hand front fender and wheel arch, and Part Five of Porsche Restoration covers the difficult restoration of the right-hand rear quarter . Part Six of Porsche Restoration demonstrated how off-the-shelf panels were used to make quick work of the restoration of the engine bay. Part Seven of Porsche Restoration jumped ahead and showed the leading work completed to perfect the gapping at the doors, trunk, and hood. Part Eight of Porsche Restoration describes the rear-quarter restoration of a panel, that you cannot buy replacements for. Part Nine of Porsche Restoration shows how the rocker panel and hood channel were replaced. Part Ten of Porsche Restoration covers the tire well repair and rebuild following a front end accident.  Part Eleven of Porsche Restoration explains how the heavily decayed B-post was restored.

Here we describe how we completed the auto restoration of this 356C floor and structural components that had seen a great deal of neglect and exposure to the outside elements.  To save time and money, we combined fabricating sheet metal and applying new parts off the shelf, after cutting out the under carriage damage.
