Mr. Spawn, a quick inventory of my basement revealed the following:
Black upper door panels, front. I believe they're '72s.
Matching black upper rear trim panels. Definitely Charger due to the window opening.
Black sail panels, '71-'72 Charger, non-'72SE.
Lower black rear trim panels, with armrests and ashtrays. No splits in the armrests.
Black kick panels.
Rear seat back, '73-'74 Charger upholstery style but you'd at least have a good frame and foams. It looks good as is, but there is some very-minor damage to the vinyl (tiny holes you have to really seek to find).
I did not find the lower door panels, but I'm sure I've got a set of them around somewhere being that I've had several black-gut cars over the years. I may have given a set to Stretch but there was another set in my Road Runner (they're identical); I'd be surprised if I gave Stretch all four of 'em. They may be in the garage. Then again, maybe beeper*71 grabbed the other set of lowers years ago; I can't be sure. Actually, those are the easiest to find.
I also have a full Slap-Stick style shifter setup, shifter to trans including floor brackets. The shifter came out of a '70 Challenger and has the Slap-Stik function, but there is no knob (this would be the woodgrain top-button knob used in '70 and '74 only, not the T-handle unit). I also have a complete shifter out of a '77 Cordoba, but that's an ugly fuckin' knob to use as it's really tall and arguably as ugly or worse than the '66-'70 console knob. It all came out of the '77 Doba with the exception of the Challenger gate. It will fit any '71-'74 B-car and any '70-'74 E-body. I do not have the console itself, however... but the shifter position is identical between all '71-'79 B-bodies so the rattle-trap console with which those cars were originally designed will fall right into place over the shifter. I took the whole section of floor tunnel, so everything you need is there short of a shifter knob unless you go with the '77 piece (don't).
