Bummer.......rust 68 shortbed

[68short]

This was a recent purchase, that I went by the pictures they supplied on a craigslist ad. It was $850, so Im not too bummed, but looks like I'll have to replace the rockers.
I can't tell by pictures of new replacements, but do they include any extra metal between the weatherstripping lip and the floor, cause thats were the rust out is?
Seems a shame I"ll have to replace the whole rocker, but the lip is gone. Everything else is wipe-off rust where I swiped an X with my finger
