Technical What’s this 40s Chevy Grille?

I have 2 grille’s, I know one is a 47-48 Chevy Car fleetmaster style (pic on top), the other is very similar but does not have the separated bars they are solid all the way across (pic on bottom), is this 47-48 car also?

 

Pretty sure it’s a 46.

 

Dang it I should have known that. Thank you Alchemy!

 

first one is not a 46, it's a 47, 48's the same except has a center verticle bar.2nd one mite be 46, not sure

 

A is a '48, B is '46 drilled for '48 T bar

 

Those aren't holes 302GMC, that's the reflection of the guy taking the picture, fooled me at first too.
And the second one is 46, matches the one on the 46 in my garage anyway .
