Vintage Peugeot conversion help and tips please

thanks Ed !! that's really helpful !

Yes stallion I'm bidding on those parts i will probably have to resell some of the stuff that won't fit on my bike like :

• seatpost (Cannondale 27.2 "carbon wrapped")
  
• brake levers (Tektro)
  
• bars (Cannondale C3 31.8 mm)
  
• stem (Cannondale 3D forged)
  
  

I will basically keep

• wheelset (Mach1 510 rims built on Formula Track hubs)
  
• crankset (FSA Vero + Shimano bb)
  
• brake calipers (Shimano Sora)
  
  

What do you recon the whole lot is worth buying it for? I tried to research online stores for the parts but some are not showing up, I estimated that buying the parts separately new from shop will be something like 250£
what do you think?

Thanks everyone for the help.
