The next things would be to determine: 1) what crankset and bottom bracket spindle taper you have if you'll be using the same crankset with the new bottom bracket. I believe the Peugeot crankarms were made by Stronglight, probably right close to ISO taper for an early-80's bike.
And 2) do you have an old English bottom bracket laying around, I would test-fit that to the bottom bracket threading first.
Determine which direction that the right-side fixed cup turns to remove.
What actually broke, the spindle?
