What front same?
LS vs. SR (both auto) = maybe - depends on engine size
RS/LS (manual) vs. SR (auto) = probably yes

RS/LS 3.0l auto - most likely 7.5"
RS/LS 3.0l manual - most likely 8"
LS 3.5l auto - most likely 8"
SR 3.5l - 8"
SR 3.0l - 7.5"
Sport 3.5l - most likely 8"

4wd system (transfer case) in Gen 2 Auto vs. Manual = same - all center locking - although physically they do not interchange.

You will need the drivers side axle also - you should just grab the entire rear differential assembly from the '95 - wheel flange to wheel flange.

yep - I did this for my '92RS... now pulled out since selling the '92 and sitting on my garage floor (flange to flange) until I find time to bolt into my '93SR.

Pump only actuates the rear locker. Transfer case is mechanically actuated with the transfer case shift lever, and has sensors to light up lights on the dash.
