You have a very good point. IDRA might also be the makers of the custom metal forming dies used in the gigapresses or the forming dies could have been shipped by Tesla to IDRA for product verification testing of the 8K unit. The 8K gigapress had to test make something. So there could be real Cybertruck front/rear gigacastings already in existance.If you are talking 2021, the only way I see that happening is this:
My assumption is that IDRA has to test the Gigapress before taking it apart and shipping the parts to Texas. If there were a few casts produced during that test, they could go to California before the machine is shipped and assembled in Texas.
Hay this is a wishful thinking thread, why not this.
