Hey everybody, this is my first time posting and I really don't know where else to turn. I've got a 71 Coronet... I know they used these and Satellites as cop cars, and cop cars recieved additional body/frame bracing. Does anyone know where the bracing goes, or how to duplicate it? I'm putting frame boxes in (I know the cop cars had these) and putting subframe connectors in... but what else was involved with the original cop cars? (I'm okay with the drivetrain/brakes/suspension, I just need to know what was different structurally)

Thanks for your help,

phantom.
