Are all manual transmission small block bell housings the same?

Looks like an NP435.
It's in a Ramcharger. But it's not the original engine or transmission that it came with.
I have no idea what it is. But when I picked it up I asked the guy if it was an A-833.
He said if it was it wouldn't be in there! :lol:

It does have Bull Low though. So maybe it came out of a 3/4 ton? IDK.

Edit; Just trying to sell the bell housing, especially if it'll work for someone that needs one for an A-833. I take it from the way the guy was talking to me he didn't think the tranny itself was worth anything.

PS it is NOT LISTED FOR SALE HERE. JUST TRYING TO FIGURE OUT IF IT'LL WORK ON AN A-833.
I been in trouble with the moderators before.
