Emissions Control System ID help, 1971 Duster 340

They were trying to contain the vapors. Possibly on all cars in 1971. I had a. Demon that had the vapor return line and no N95.

Do you have N95 on fender tag or broadcast sheet?

do you have the 2” pipe on the driver side inside the trunk? Runs up behind the wheel tub. This is where it would go Through the floor and up. See top bracket up higher?
