Nice looking project. What calipers did you end up installing?
Mafac 2000's (with Modolo levers). I am not happy with the way the fenders go under the fork/seat stay bridge. They suck pretty close to the wheel, then flare out a bit. There isn't much room, and I had to crimp the front to get it under the fork. I'm just going to have to futz with it a bit.
