The TX9 - "black" N94 HEMI Challenger R/T was JS23R0B336419 - Y14 "SOLD" car
(E74, D21, A33 & N94 are its ONLY extra cost OPTIONS)
3266.00 + 1116.45 + the hood(~$150) = ~$4532.45 + destination charge
HEMI 4-spd w/3.54s - black interior, '450 wheels, manual steering, manual drum brakes, NO radio, NO console, NO vinyl top, and NO stripes.
I have a copy of the b'cast sheet - SPD 512 & VON 076275.

Sounds like a "racecar", that's the rumor - it was raced/hacked to death in the '70s & didn't survive. It was in the pacific northwest (note the VON).
