You've definitely got me inspired to get off my lazy ass and get my PX-10 back on the road. Well, the frame was restored five years ago, I think it's been hanging in the bicycle barn long enough.
Where it's going to be difficult . . . . . . My frame is a '77-79 (long after the Bike Boom, well into the Bike Bust when you couldn't give away a 10-speed), and while the specifications aren't all that different, the devil is in the details:
You're using a Stronglight 93 crank, mine takes a Stronglight 99. The few I've found are invariably in Europe.
Derailleurs on yours are Simplex Criterium (metal reinforced plastic), mine are Simplex SJ's (alloy, happily I've got those).
Fortunately, we use the same levers. Um, maybe a slight difference in small parts, but you'd need to be a real anorak to notice.
Your brakes are Mafac Competition, I'm using a set of Competition that are based of the mid-decade Mafac 2000 redesigns (I've managed to find Peugeot branded calipers, still looking for levers, not exactly but it'll pass until I get the perfect ones).
I haven't even bothered with the wheels yet, as I'll use a set up of Campy Tipo/Mavic wheels (an extra cost option on the Gitane Tour de France) just to get the bike on the road. Definitely have to look for Maillard hubs, still not sure if they're the standard freewheel or Helicomatic (I hope not the latter, as I lost all of that stuff in the fire).
