I know of the existence of four 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 JH23H0B - blue automatic JS23N0B - green R/T automatic (pic below)
I've heard a rumor/seen a pic of a blue 440 SIX PACK car in Texas, but no proof of factory installed hood. I'd "assume" the 440 Six Pack cars would use the T/A air cleaner.
