Is there a VECI label on the radiator support?

Vehicle Emission Control Information label - it's the white label on the top of the radiator support that shows spark plug gap, ignition timing and ...wait for it... emission hose routing.   :)

It is still there. Looks as new as the day we picked it up back in 87. So it says emission hose routing. Is that all of the hoses? If not then I need one that shows all of the vacuum hoses
