I plan on cutting out my rusty rockers and doing the 2"x6" mod, also will be doing the floor pans at the same time. I have holes in what I believe to be are the inner rocker panels. I really cannot find any information about replacing these. I'm assuming that I have to use some of the inner rocker panel to weld to the bottom of the 2"x6". I pretty much have no metal from the floor pan out. Any hints tips or advice. Thanks
