Scott, here's the thing... You could "get away" with using your existing inner cup, but the damage is not good. And... The splines are wore down.. If you're tight for money, take a thin file to the splines to clear the "path". The "cup" needs to be de-burred something fierce as well...Will my Inner CV Housing be ok with some small damage from cage fail and axle tore up the housing a bit. Want to see if I replace with new rebuild kit that it will hold up ok.
