Where exatcly do the decals go for.....(Images added)

[Snake Eyes USA]

Hi Chevy/GM Family,

Cant tell you what a huge pain in the ass things have been to registering my truck in Cali. from Canada.
A huge thread in time will come when I see a light at the end of the tunnel. Still no light.

Anyways, two important questions. I searched through the forums before asking. Results were not clear as day. Also couldn't find clear images.

Where does the emission decal go on a 70 1/2 ton truck? See image 1.
I read possible somewhere along the radiator frame?

Where does the emission decal go on a 72 1/2 ton truck? See image 2.
I read possible on driver side top of fender wall and somewhere in top center area of radiator/radiator fan?

Is there a thread in the forums that has pics of just engine compartments? So I can try and get decal reference locations?

Thank you.
