Anyone familiar with transmissions for Dodge Maxi-vans?

['74 Sport]

My son is planning on retrieving a 360 V8 from one of his
grandparents' extra work vans to swap into his new project,
a '74 Gold Duster.  What type of automatic transmission
would be in a mid-80s Maxi-van, and will it fit in his Duster?

I'm sure it's a 727, and if so, it will fit a Duster.  The 727 has a kickout by the filler tube and the 904 is straight.  Here's a 727:


Here's the pan gasket:


And the 904:

727 - That's a good thing!
