Help decoding this bell housing !

Ahh Thank you !

I forgot to add that my transmission is a 64 to 66 A833 will either of these bell housings still fit ?
Very similar- for '72-'74 A body and '70-'74 E body.

Same caveats apply to this one as to the first one you showed as far as fitment into an early A body.
