ripped out the carpet and have questions

so after pulling the carpet i found this sticker that let me know i have a 230 in my van and that was nice but also it seems like there should be some kind of brace or something on the non window side of my van. does a wood strip go there? and if so how do i install it? 2wo piece?

Just the floor, the ribs and the roof rail as shown.
Take a look at other's projects for pics.
If you want to add an interior, additional stuff is a good idea but they were very basic from the factory. Just enough to hold shape and seal! All extra capacity was for the load.

ok thanks. that space between the outside panel and ribs seemed suspect to me. im planning on sheeting this in luan door skin and wanted everything braced up and dialed before it gets covered up.

I think my 69 has a brace there, I'll look later to know for sure.
