From what I have read about the aluminum pieces for the early Pontiacs, it was a difficult process with an extremely high scrap rate. The parts were stamped usually on a Saturday, first shift, by the craftsmen with the most experience operating the presses. The aluminum required different techniques and pressures to avoid tearing and to still get the crisp feature lines they needed. The dies used were for the steel parts and did not have the features in them to produce aluminum parts in great quantity. If I remember correctly, the scrap rate was something like 1 usable fender or hood for every 15 pieces stamped. So it's not a slam dunk simple deal.
