Rocker Boxes Install

[tims71]

I was wondering if anyone here knows how to install the rocker boxes. Mine were taken off to install saddle tanks, which have since been removed and I noticed that there is flex in the body and the doors rattling. I have ordered
all of the parts but need to know how to install them. Any help would be appreciated. Maybe diagrams or where to find diagrams??

On my 75 they're welded to the cab, rockers and bed supports. Not sure about a 71, I imagine it's the same way.
