38 Plymouth sedan new custom tailored boot floor and inner tail pan

The 38 Plymouth has a Jag diff and aftermarket 32 Ford fuel tank so the old rusty floor had been removed.  To give the floor some strength I went with deep ribs because there was no frame under the floor and not room for a frame between the chassis mounted fuel tank and the floor.  The step down at the back drops down to line up with the bottom of the rear sill panel to box it in and make it resistant to body flex once its all welded in.  This was all formed in one piece, how ever to install it the rear sill panel was cut out, it was all rusted through anyway and required a custom formed piece too.
