After some research,I orderered 1/4 inch ball joints NOS.Everyone on line said that was standard for campy record rears.Maybe they"re not.I couldn't notice any difference from the old ones but they were pretty messed up.The wheels do spin smoothly with the new bearings.Anyhow thanks for those sources but I ordered another axle from Niagara for$5.99 that seems to be acceptable after I cut it.{Wheel Master Quick Release Axle - RR, 10 X 26 X 135 X 146**I hope that 26 stands for TPI cause I already ordered it.
