Differential swap

[Mikecoyotegen3]

Apologize if this is in search i didn't see it.

I have 2020 gt pp auto 355s, I want to swap to 315s, I found a cheap diff from an ecoboost with 315s is that the same differential as a gt or is it diff spline and open diff. I'm boosted I need more gear

what year is the eco? And is it auto or manual? As long as it's >18 I believe they are all interchangeable.
