I have a 71 with the ashtray at the rear of the console. As usual cheaper to have 1 in console than 2, 1 on each rear armrest. Save at every corner they could but charge more.
I have an early '71 Challenger - 8-70 - that came with the seatbelt storage console. Assuming they had a leftover '70 consoles before switching to ashtray console. Found some other '70 pieces installed in the car, as well.
My September of 1970, 71 Challenger has 70 console ,70 bucket seat backs and 70 interior rear view mirror. It’s a R/T with carpet on the door panels, I have had some people question the door panels.
I also saw a 71 R/T with a VIN less than 100 from mine with the same console, mirror and seat backs but I didn’t lay the door panels because that had not been brought to my attention, I assumed all 71R/Ts had carpeted doors.
