I know of the existence of four documented 1970 non-T/A Challengers built with the N94 fiberglas hood.
FWIW The three listed below that still exist also have the "J81" rear spoiler.

JS23R0B - black R/T 4-spd "RIP"
JS23R0B - red R/T automatic (not the ebay car)
JH23H0B - blue automatic
JS23N0B - green R/T automatic (pic below)
