The size on the steering box should be the same for all 1980 and newer jeeps. Its the GM metric O-ring fittings.
Now the hoses themselves may be different from 87-90, and 91-95 because of different steering pumps, however the fittings are still the same metric O-ring. Just the length of the hose, and the bends on the steel hard line part of it would be different between the years and different engines.
