A904LA transmission issue

I looked for the stamp date on the casing but couldn’t find anything. The engine is a 67’ 273 and I have a 65’ body so I’m thinking maybe it’s also a 67’ A904LA but I’m not 100%. I found a number on the side of the casing but there’s no reference I can find that explains it (2464450). I can see another number but it’s super faded
It's not. It's a 65 and back transmission as they are cable shifted.
