This is looking great -I don't know which of us is further along
The Flite saddle will look fantastic on this. I still have a couple kicking around, and until I retro-ized all my vintage rides with 3ttt or Concor saddles, they were all equipped with Flites. I first started riding Flites in 1994 and only in the last couple-three years began to go back to the old-school stuff.
I can hardly wait to see the finished bike - and I also agree with your wife: use the Campy crankset bolts
