me either on it being finished part.
the side panels are the key part. they'll lock the bottom of the back/front panels in on the sides and the plastic locking pins will hold the centers of the front and back. the sides will have small sewn hand pulls up near the to for easy removal
I am going to add a partial removable floor to the trunk and build it up so it'll be flat when I put in the larger tire (I have not measured how much higher I'll have to go or even if the 14 rally with 205's will fit) if it does fit I'll add a riser and re- floor it with lift out or hinged ply and carpet to match the interior carpet color that way I'll have a couple of inches of storage space that hidden around the tire well and can store tools and repair items in that area without it looking cluttered.
