Dont forget the "ba$tard" Challenger shaker hoods that were manufactured with a 70 top skin and the underside 71 style crush zones.
They may have been manufactured during the transition period over to the crush zones.
Most of them wound up at the Chrysler depots.
Hemicar1971 you should recall in 91 or 92 at Englishtown, Downer had 6 or 7 of these NOS hoods, and 2 of them went home with us.

Many years ago one 'theory' I heard on halting the 70 Challenger shaker hood production, and this is only speculation,... is that the underhood bracing broke loose, be it in accidents, or perhaps during crash tests.
That coupled with Ralph Nadar at the time crusading for saftey in the automobile industry, could have resulted in Chrysler rethinking their hood structure.

Agreed... Ola's red/red
