904 or 727 SBM Inspection Cover?

[Odin]

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!

The one you have pictured is a 727 The small plate is for a 904. 727's are different for different diameter converters. Look how wide the 727 I have pictured the arc is for the converter bolts to travel without hitting.

thanks for the fast reply. So I have a complete SBM 727 plate and cover and the remaining small cover is for the 904 plate? I will create a post asking if anyone is selling the 904 plate then. Thanks again!

is this plate any different than the one in the earlier photo?
