70 challenger rtse radio and wiring harness

[mopar70rtse]

Hi, I'm looking for a factory AMFM stereo 10 amp with thumb wheel knobs.
I'm also looking for radio wiring harness for rear speakers that's a 4 wire, that runs from main harness to rear.
Also looking for the wire connection for left and right front speaker, that runs from speaker to main radio wire harness. If you have complete radio wiring harness, I will be interested if I can't find them separate.

Thanks
