Just spoke with the boss... there are none of those numbers on the axle and that's why he only gave me the casting number... And the pinion is broke out of it and missing so I can't rely on that either. Does anyone know what was in these trucks out of factory? I'm talking to the GM Heritage Center right now but they take weeks to reply...
