Cant Find Replacement 4x4 Spindle Bolts

[bhammer]

I am rebuilding the front end of my 72 GMC 4x4 after it was in an accident. The driver side wheel hub assembly has broken off at the bolts on the spindle. I have hammered out the broken ones back into behind the spindle and I cannot find replacement spindle bolts. These are the bolts that bolt up the the wheel assembly. Does anyone know where I can find replacement bolts? I've looked at all the major autoparts stores and they can't find them. One person told me the dealer can get them. Haven't tried them yet. Any help would be greatly appreciated.
