I believe these were used on a 70 challenger 440+6 car with the n94 option (T/A hood) when it was substituted for a shaker. They probably made a bunch but, as we now know only a few challengers did come this way. I`ve seen one like that years ago on a original car. Not the orig owner of the car though.

The cut version being discussed here was never used on an N94 Challenger 440-6.
Original blueprints exist that prove so.
Since the A12 air cleaner was one piece stamping( not counting the drain corners and extra tubes ) Fram, Chrysler's air cleaner supplier, would then have had to trim the whole excess lip area and discard it.
Cant see the wasted time and material for that ever happening.
The N94 was never 'substituted for a shaker'...N94 was an option just like N96.
