Starting to replace my rockers, have ???'s

[KrazyKevin]

Sorry if this is a newb question, but I see so many rocker pieces that I don't know exactly which I need. I just ordered the Goodmark outer rocker panels from summit. I have a feeling I'm gonna need more metal. Here are a few pics of what I'm dealing with.









To me it looks like the outer rocker and a portion of the cab. But after looking at many websites selling rocker panels, I see a few items related to the rocker panel area. Is there a website that someone knows that has a detailed view of this area? I have the factory assembly book but it really doesn't get into the cab since its welding together.

Thanks

Kevin
