Wanted: Lightweight stuff

Hey, I wrote about my searches before, but couldn't find anything so I am trying it with a combined search again. I am building up a 1983 Moser Aero which currently will weigh ~8kg. What I am still looking for are the following things:

• 32 hole OMAS REAR hub, also FT Magnesium hubs I'd like to try. Can also just be the hub body.
  
• Selle Italia Superleggera or Concor superleggera, needn't be in good shape as I like to try to get it's weight further down
  
• CLB duralinox brake housing set 85g (silver)
  
• Ale bottle cage 35g, silver or black
  
• SR Royal superlight stem (80-100mm) and seat post (27.2mm)
  
• 1983 Moser jersey GiS Gelati in L (50cm armpit to armpit)
  
• Ale nylon pedal straps, black or brown.
