Hi - in lieu of coughing up for a new bike I am planning to to rebuild a Vitesses 12 speed I've had since the 1980s - the frame is double butted chromalloy (carbolite 103 ?) and a little lighter than the aluminum frame I am riding on now. Problem is Peugeot is out of the bike business. The easy part is the sandblasing and painting of the frame.. The hard part is finding modern components to fit the frame, etc.. which I don't have much experience with.. Any suggestions on where to start appreciated.
Thanks in advance,

The first thing that I would do would be to check to see if an English threaded bottom bracket will work. If it turns out to be French threaded, I think that I'd drop the whole idea and look for an easier frame to play with.
My Peugeot (85' Ventoux) more or less conformed to standard (non-french) even though it was built in France.

Some Peugeots from around the period of yours are Swiss threaded in the bottom bracket. If this is the case, a decent shop can tap the Bottom bracket threads out to English. If it's Swiss and the cups are okay, you can always keep them; although you might have spindle problems if you Switch to Japanese components. However, it is quite possible your bike is English in the BB; I doubt it's French, as Peugeot switched their BB threading to Swiss right about 1980, and your bike is certainly later. I'm unsure when the switchover to English threading was.
If it is Carbolite 103 (plain-gauge carbon steel), don't bother, unless you can find cheap used components for the upgrade. If it really is double-butted CrMo, go for it.
Several years ago, when I changed cranks on my PKN-10, I forced an English-threaded (24 TPI) fixed cup into the Swiss-threaded (25.4TPI) BB shell, and this has given me no problems whatsoever. Other BB options include reaming and tapping to Italian standard and cartridge BB assemblies designed for threadless assembly into a (presumably stripped) BB shell.
