If by 80's Pug you mean a Peugot, then I believe a nice pair of centerpull Mafac Racers or Mafac 2000s would be period correct, if you can find them on the bay or in the parts bin of an old LBS. I have the 2000s (with drilled levers) and a brake bridge installed on my "winter" bike. Made a huge difference when I installed some KoolStop salmon pads on them.
