4 Pinion is stronger. Make sure the gear's in the rear end are the same as your's. Good luck!

I believe that the 80 frame is narrower than the 87 so you may have to move the mounts

The diff itself has 4 pinion gears or spider gears instead of two. You can put a 4 pinion diff into either axle housing.
