You should be able to run (the idiotically named) DOT 5.1 brake fluid, which is virtually always DOT 3/4 compatible. But not as good as DOT 5.

End of the day who cares, if you want to keep the car original just change your DOT 4 fluid every 3 years. As long as the brake system works properly and you're not driving down mountains you won't notice much difference aside from the shorter maintenance schedule.
