904 or 727 SBM Inspection Cover?

I need a complete transmission cover plate with the small inspection cover for two builds; one 360/727 and one 318/904.
Is there a difference between the two cover plates or are they the exact same?
I know there are at least two different size inspection covers so I assume there are at least two size plates.
However I do not know if there were different for various years or because they were made for different transmissions.
This is what I have in my parts boxes, but I need one complete setup for each build.
Please tell me what these go to and I will then post a wanted listing for what I still need.
Thank you!
