Radiator Support Numbers?

Hello,
I've read a few posts about checking the #'s on your Radiator Support to match it up to the car ... But I've looked all over mine and can't find the darn things...

Where on the Radiator Support should this be stamped?

Thanks!

Usually on the top or on the engine side of the radiator support.

I have seen the number all over the place, from down low near the battery to about mid-radiator under the coolant decal.
