The bike is an 86' Centurion Facet. Gorgeous bike, I can't wait to take her out!

Anyways, the measurements I got are:

1. Dropouts - 4.942" = 125.5mm
2. BB thread - 24? (I used a Snap-on thread tool from a tap&die set)
width is 2.793" = 71mm
circumference is 1.325" = 33.7mm
3. Headtube - 1.022" (upper) and 1.041" (lower)
4. Brakes - squeeze type for rim sidewall, I don't know the official name but they are not cantilever brakes
5. Seatpost - 1.94" =49.3mm
6. Wheel size - no clue, I assume 700cc because it's a road bike

I know this is going to sound like blasphemy to a few out there, but I want to outfit this c&V bike with modern components.
