Power steering fluid
The ebay link I found for the old set here actually included the term "vintage" in the title. Couldn't hurt to flush the old fluid in the system if it is 20+ years old. There is a whole process for this with the PS system which comprises a few bottles of fresh, getting the car in the air, turning the wheels lock to lock numerous times to work the old fluid out and replace with fresh. So I also don't blame you for topping up and driving off.
