Based on the battery tray pics - or what is left, I question the sellers statment "...car is rust free according to seller (longs, floors, etc.)..."
That ain't "rust free" ...
The rust has almost certainly gotten inside the pass. side long. I'd carefully check the back of the long from the jack post backwards. Lots of poking with a screw driver.
Also, it appears the rust has eaten into the pass. side suspension ear. You need to look for holes and cracks there.
Lastly, move the pass. seat all the way forward, remove the carpet behind it and poke the hell out of the floor and the edge between the floor and the long. Do the "crunch" test on the lower ribs on the floorboard. Don't let the factory paint fool you in that area. They painted OVER the sound deadening tar mats and the rust will be underneath the tar.
