This is why I named my self rustbuket! ahhhhh rust everywhere ! luckily i live near classic auto parts in OKC
www.classicchevroletparts.com/so i saved on shipping except the rear pillar or "b" pillar, had to buy that from LMC. Id guess about $200 in replacement steel on just the driver side. Dont waste your money on the inner rocker it is too short vertically unless you just want scrap metal to fill holes with. i used the floor edge repair piece that includes the inner rocker and a few inches of floor for the whole length of the cab.
