2004 Mach 1 Gears/Differential - will they work?

Hey guys, been a while. Still learning about my car so here goes my question...

I've got a buddy who is giving me a set of 3.55s and the differential out of his 2004 Mustang Mach 1.

I have an 8.8 with 3.08s according to the tag (to my knowledge out of an 88-93 Mustang 5.0) installed on my car.

Considering that nothing has been done to this 8.8 or anything in the rear for that matter, I should have 28 spline axles, right? And the 3.55s and Mach 1 differential install should work? Thanks guys.

As long as it's a 28 spline differential unit it'll work fine. The gears don't matter as any 8.8 gears fit any 8.8.
