2012 Challenger R/T Classic edition sale/trade

Yeah, I saw the pictures, nice car. I've already got a 70 340 Swinger so I'm looking for a little more variety in my fleet. I would really like a B or E body just because it makes swapping the Hemi easier, but I'm still considering anything until I do a trade. I've had quite a few offers.
how about your duster what motor and tran is in it and does it got 8/3/4 rear
