What Rear End did I buy? Swap help!

Long story short my son hit a center guard rail in my late father-in-laws 2013 Mustang GT 5.0. When we got to the car the rear tire was across the free way. I have already replaced the front control arm, strut link, and steering link. You can see the rear end in the picture below. Initial plan was to replace the axle, but I was worried with the bend in the part around the axle that I wouldnt be able to do it. I found a rear end for sale 3 hours away and went and picked it up. I have done a decent amount of maintenance, but never anything this big, so didnt really know what I was looking at. You can see the picture of the sticker below, but I believe it is off an older V6 mustang. I have removed the rear end out of my car and the look identical other than the one from our car is a 3.15 gear raito, and the bolt pattern in the plate for the drive shaft is different (mine has 6 smaller bolts, and the replacement has 8 bigger ones). I was told by a family friend that he believes it is from a v6 because of this. I am thinking I can swap the plates, replacing the pinion seal and nut in the process. Should this be ok?

Even though it's from a V6 it may swap out ok. There's quite a difference in the gear ratios that you may or may not like. As long as the rear brakes can be swapped over and your pan-hard bar isn't bent as well I can't see why it won't work. Someone may have a little more knowledge on this than myself

That should swap out fine if they're different
Do you think I can swap the the flange that connects to drive shaft or would I need to find some kind of special conversion flange?
