I checked my stash and the onle close BB axle I have is a Campy NR 68-SS-120. It's aprox measurements are overall 112+mm, 30x50x33. How it might fit your DA arms I'll leave to an actual trial to see. But the tapers share the same angle and generally only how "thick/wide" and how long the tapers are is where the slight differences are. Hoe deep into the arm's taper will axle end up is also somewhat dependent of the wear/stretching of the arm holes.

PM me if you are interested in this axle. Sorry I have no available cups, the last of mine were made into frame painting handles. Andy
