A 1968 ss350 should have emission, air cleaner (eng/hp). I think there is a decal on the side of the closed air cleaner also. NO Caution fan (ford). It should have a tag on the hose to the power booster if so equiped. Nothing on the doors. Glove box has the tire decal (not recommened to change if nice). Trunk lid has jacking instructions. Trunk lid will have a decal if equiped with posi. Coil springs & leave springs will have decals as well as shocks. I think that's it....Joe
