Can anyone identify my rear differential? 8 3/4 but wrong markings???

Was thinking some family of the 9" Ford.




Start with looking at the bolt Pattern on the housing.



Here is a Mopar 8 3/4 housing pattern.


Looks like your housing opening Is round with only 1 bolt at top.

Mopar has the flat top Pig with 2 bolts closer at the top.



Would say your's is a Ford.
