I have a question of why a rear end will drop down whenever the Mustang goes into gear? Is it the transmission mount or the differential?

In what way does the "rear end" "drop down"? Are you talking about the rear of the car squatting on acceleration? Or is perhaps the front of the axle housing itself (the pinion end) pitching downward...?

It from the rear end that drops a couple inches when it is put it reverse haven't seen it do it when in drive.

Say again?

So when you turn the car on you put it from park to reverse the rear end drop a couple inches

Putting it in reverse sure doesn't sound like acceleration squat then. But I still can't tell if you're talking about the rear of *the car*, meaning the trunk/bumper/body, or if you're using "rear end" to refer to the axle assembly itself. For all I know you might mean the rear end of the driveshaft. Can you post a video link showing what it's doing?

Well from I saw it the whole back end haven't check to see if it just the differential
