Restoring a '70 GTO and would like to verify she hasn't been tweaked at some point in the past. Anyone know where I can find the frame specs (I think it's called a "drop sheet"

? Many thanks! </div></div>
I may be speaking out of turn but I believe the chassis service manual/unit repair manual usually has a picture showing significant frame dimensions and callouts.
Also - there may be a chart in the assembly plant "assembly manual" (aka "PAD sheets"

but I'm not sure if they are readily available for 1970 A body.
