72 455 intake casting numbers, same / different by model?

Hello. Looking for some help with replacing incorrect manifold with correct one. Are the casting numbers on the manifold different for Electras / Rivs/ GS or are they all the same? I need to know what the correct numbers are for a 72 GS 455 A/C California car , auto trans. Thanks for any help, Kevin.

 

12383232 = Cal 72 455. Non Cal I believe had a different number.
