Location for Service Parts ID & Emissions Labels

[DVan]

The P30 Chassis Manual states that there are labels for emission equipment (vac. hose routing, evaporative, A.I.R., etc.) and Service Parts Identification of equipment options (fuel tank size, etc.) supposedly attached to inner body panels or under the hood. I've not been able to find ANY such labels; only the VIN tag riveted to the driver's door of my 1988 Windcruiser 32RQ. Any suggestions?

All of the emissions hose routing and information is usually on a decal on the air cleaner.
