The change in 82 was due to switching from SAE flare fittings on the power steering lines, to Metric O-ring fittings. If you use any GM unit from 82 and up, you'll need to use adapters on your hoses to connect it with your power steering pump and steering gear.

The power steering pump has an outlet fitting in it already that can be swapped out for the newer metric fitting. This would make one of your pressure hoses a stock 82+ part number. The other pressure hose that goes from the 82+ hydroboost to the 78 steering gear, will require some adaptation to make it fit, since both ends aren't the same.
