If its a rotary pump, like what would have come stock on a 1986 motor, I do not believe that the internal parts are available from the dealer anymore. There are no real "serviceable" parts in there.

I'd check to see that the vanes are not stuck, and that the internal surface (upon which the vanes ride) is not rusted/pitted, etc.

If all that checks out, then it should work just fine.

Did the car sit for a while? if so the vanes may just be sticking. There isn't much too break in them, so taking it apart to clean and a apply a tiny bit of light oil. Just be very careful removing the rubber hose that is attached to the pump. It's very easy to break the plastic fitting it's clamped to.
