nope, I saw no foam, just a really top notch job of plastering the rocker panels with bondo. I mean I've pulled off 1/2" thick layers of the stuff. notice the pic I have that shows the entire side of the rocker panel. notice the lack of jack holes? yeah, the entire thing was created from bondo. I really feel for the poor sucker that bought this car thinking it was sound. I'm glad I just need some parts off it. I'd hate to need this for transportation.
