'73 Rear Frame Rails

[David429]

I need to find the specs for the rear frame rails on my '73 coupe. Is there a manual which gives dimensions or does someone have this information?
I need the actual dimensions of the frame rail from the torque box back. Mine are rusted and I have patched them with metal bracing.

Do you have a factory shop manual? If not, youd have to find a Ford assembly manual.
