Iv tried looking on the internet. Thats what led me to here so if anyone knows, or knows a good place for me to look. Id be gratefull.

Is the car an original 5.0 or a V6? If it's a 5.0 then it's an 8.8 with a 3.08 rear gear, more than likely. If it's a V6, then it's a 7.5. Hope that helps....if you can, take a pic of it and post it. Later.

its a original 3.8L v6. so im taking it its a 7.8. So when i put in my 5.0 i have have to upgrade my rearend aswell huh? Cuz the rear end has 121k mile on it now. And with the more HP it might twist it when i drop the clutch. And yea i will get a pichure of it on here soon. And thankls for your help.

Yeah...if you intend on "dropping the clutch" often then that 7.5 rear won't last long.
It will, however, last a long time if you drive normal...but what fun is that?

the 8.8 and 7.5 are easy to tell apart, from underneath the car looking at the differential cover, a 7.5 (or 7.8 as you put it) will have a shape more of like a rectangle, with two flat sides top and bottom while the 8.8 has a more round shape with all sides of the diff cover being equal in length with a more of a square or circular shape. All v8 mustangs 86 and later got the 8.8, sorry dude, I think you have the 7.5, the axles are interchangeable being of same spline (28) and dimensions, but who cares, you should always get new ones anyway, but just in case yours are in better shape than some junk yard rear you pick up, you could use your axles.
The 8.8" is a mean rear, a dime a dozen, and easy to swap.
Hope this helps.
