Rear end gears? Depends on what aspiration your Bird is. 3.55's are pretty much all around good. 4.10's are more for S/c'd applications, and 3.73's are more for non supercharged applications. I may have that backwards, and if so, correct me. Depends on what gear you want to be in and RPM's per speed.
If you meant bumper, I believe that 94-97's will interchange.
Please elaborate on what 'rears' you are talking about. As far as rear ends, I dunno...
