Dan,
We stock Remy rebuilt units. The difference in what we carry & automotive stores (A-Zone, OReillys, Advance, etc.) is that our Remy units are 100% rebuilds. The retailers best rebuilds are not. The electronics are not replaced if they test out at the time the unit is rebuilt. Remy rebuild & packages for all of them, including ACDelco.
If you are unsucessful having yours rebuilt, keep us in mind if we can help. here's a link to our website.
