Yea, I did try threading both in at the same time, NO GO! By the time you are about 5 or 6 turns in, everything starts to realy bind. The cups are quite pitted, so if this can't be corrected I guess I will get more cups, a shorter axle, and a new crank set.
Heck, it may not be worth the trouble, and expense at all!

I was thrilled to find it had English ISO cups! It is an older Motobecane with 700c wheels, rides smooth as silk, and don't look half bad.
