Dude, I feel your pain. One of my favorite bikes (of 8!) is a '75 peugeot mixte and can't get the headset right. It loosened up on me four times in one ride today, and I've taken to carrying a headset wrench in my pannier. Of course, no one makes this headset any more.
But getting to your problem. The BB is a concern I've fretted over as well. And I just finished putting about 15 hours into another '75 peugeot, where someone put a JIS (Shimano Biopace triple mountain) crank onto the french spindle (omg!). I discovered this belatedly, after trying to solve a shifting problem. The crank had a left/right wobble due to the inherent japanese/french incompatibility, and the Biopace has a up/down (out-of-round) rotation. When added, both effects are quite psychedelic! The FD didn't like it though.
There was a thread about this spindle/BB problem recently on bf. I'll try to find it and get back to you. Another source is my neighbor and Peugeot guru. He actually bought the expensive Phil Woods for one of his, but it was a 531 frame - a little easier to justify than mine. But he had another source. Oh yeah, I think he said Velo-Orange has at times carried something more reasonable, but it's not always available. Then, there's always ebay.
