For Shaker Challengers the date was 4/15/1970
Not sure if cudas shared the same date as the header panel to hood gap creates an automatic crumple zone.
From what I recall, the Cuda wasn't initially required to meet the crash requirement imposed interim on Challenger production because of the header panel, but that later Corporate added the crumple zone to the Cuda production in mid 71 production to head off any potential problems from the Feds and that the early 71 Cuda production models used up 70 production unit stock until the retooled Cuda hoods were released for production?
