Transmission Identification Help Needed

I have a truck with the 400M motor in it. I had to remove the tranny because the front seal was leaking pretty good. Anyway it's got a square pan with 11 bolts and the dip stick screws into the side of the pan. It has the following numbers on it:

C8ZP - 7D027-A

10A

17

D50P7006AA

I was told it's an FMX but I want to be sure. I was told it could be a C4. The only thing I can figure from the numbers is it's a 1975.

Thanks

C4 11 bolts, almost square, so it says here:

Separate bell, aluminum case.

MX trans would be aluminum bell, iron case IIRC.
