Hey all Im doing the body work on my 72 k5 and there are these seeemingly useless boxes behind both my rocker panels and basically under the floor. I think there called rocker panel boxes ? Anyway they just bolt in and they're rusted to [censored] so can i take them out without any adverse affects on say floor rigidity or panel durability ? To me it looks like a lame gm design because they just trap water and debris which rusts out the floor boards. So please somebody give me the scoop.
