The "hangers" in this case were like coat hangers, and each one held a sleeve of clear plastic with all the parts runners for a given mold inside. Round 2 had apparently contracted for an extremely well qualified individual to go through the tooling bank and run test shots of everything there.
(Reportedly this same exercise revealed all the parts of the original AMT California Hauler kit, which were welded off in the Peterbilt 352 cabover tool (e.g., it was actually a shared tool incorporating individual parts for the 359, individual parts for the 352, and parts common to both kits. As most of you know well, the California Hauler 359 was rumored to have been scrapped decades ago.)
The pictures I saw clearly showed most of the components of the funny car version of the '64 Olds. TIM
