Bolt in - yes
Limited slip - yes
Disk brakes - Either get the master cylinder from the same car since it had the rear disc already (Maybe the 94-up one is the same)
- Or upgrade to a different master cylinder and add a proportioning valve

Not sure exactly what you meant, but the stock master cylinder cannot suppy the demand of the 4 wheel disk setup.
