You can fit anything into anything with enough time & money, but I think you'll be a lot better off sticking with a factory option like a12rag mentioned....seriously, even if you have to look hard & ship it. Most "newer" cars are front wheel drive anyway.
You might also see if you could pick up a narrowed 8-3/4" or maybe an A-body 8-3/4" if you plan to race the Mirada....maybe check the race section. At least a few Miradas have been turned into drag cars.
And to answer your question.... the "easiest" rear end to swap would be another rear end just like the one that's in there now.

I might be getting a 70 b-body 8 3/4 . That's what I did on my 82 Cordoba. A couple things to be aware of though. Your Mirada uses an isolated rubber mount setup on the rear end. There is a large plate with rubber in between the spring and rear end. The hole in the spring perch is very large so the new rear end won't just bolt up. If you want to do away with the isolated setup, you'll need to buy some old style shock plates. With the isolated stuff removed, the new rear end will bolt up just fine. What I did was retain the isolated setup but had the spring perch holes enlarged to match. I don't remember the exact size of the hole but it's large.(1 1/4" or something crazy like that) With the perch hole opened up, the rear end will bolt up and you don't need to change the shock plates. Secondly, the spring perch centers are slightly different between the 7 1/4 and the B-body rear. Maybe 1/2" or so. Some people just push the springs in 1/4" per side and don't worry about it. That does put pressure on the bushings but I don't know if it's enough to worry about. You could have the perch holes redrilled to compensate for that.

1966-1967 B body 8 3/4. Open the spring perch holes up. 1968-1970 rears a little bit wider but will work. Spring perches are 1/2"off but it's not a problem at all. Driveshaft will move forward 3/4" roughly but most cars thats no problem too.
