Rick, don't know if this is applicable to your problem, but my front-end has an assortment of different manufacturers' parts. The spindles are from a 68-71 Camaro and in order to get everything tightened down, I must deepen the grooves (can use saws-all blade or machine) on the castle nut, which lets the cotter pin line up with the hole on the spindle.
