[CR]Rear Geometry on Race Frame - BB sizing

I am building up a used frame that some of you might be familiar with - the

Huissoon Sport labled racer as seen on Wooljersey http://www.wooljersey.com/gallery/HuissoonSport55cmRed (Thanks for keeping it up Mark, SOMEday I will get a digital camera). It has 126mm rear hub spacing and a 68mm BB width. I figured that I would g o with a standard C Record 68-SS bracket set but I was wrong. English threads

by the way. At first I thought I put a P axle in, because the short side would not clear when my 170mm NR cranks were attached. That is, the 17mm side of the

axle caused the crank to strike the bottom stay. - A standard Campy road axle is 17mm on the left and 20-25mm on the right, depending on if it is double or triple. When I flip the axle the 20mm side clears but the 17mm does not. I am campy centric and at a loss... Its a beautiful frame, and I would like to put it on the road, so if you

have any ideas please help me out.
