Transmission number

Hi I'm trying to ID this transmission that is mated up to a Ford 460, year is 1977. The number on the transmission just 1/4 inch rear of the transmission fluid pan is 1 120B7 78723 Does that indicate a Transmission type? It's a different motor/trans than what vehicle came with. Its in a 1959 B-600 School Bus. The transmission is leaking fluid and I may need to get some parts for it.
Thanks

In 77 I think the only automatic they put behind a 460 was a C6.
