It is not so important to change it. Think of it like the differential (rear end) in an ordinary car. The oil doesn't break down and it doesn't get full of products of combustion, it is just a gearbox. Most important is to make sure the level is correct. Since the car is 20 + years old and you don't know when it was changed last or what was put in it, it is no big deal to change it. 85/90# gear oil is what to put in. You do need the adapter to remove the drain and fill plugs and inspect the drain plug for any debris if it is the magnet type. If it isn't you can order one and get some new copper washers. You should drive the car before draining to get the oil warm-hot so it drains easier and all the dirt is in suspension so it comes out with the old oil. What is of greater importance is the brake fluid. If it hasn't been changed in along time when you do change it you will probably soon find the calipers and master cylinder leaking. Expect to do a COMPLETE cooling system service replacing EVERY hose, water pump, belts, pulley bearings, thermostat, gaskets, and seals. In many cars these [arts are still the origionals!
