Audio Systems: 1972 ford gran torino, ford gran torino, 1972 ford gran torino

Question
I just got a '72 torino, it's not a fast back. it only has an AM radio. i want to keep it as original as possible. i was wondering if therewas any way to get a remote controled audio in the back without cutting up the interior.
if there isn't where would the most unnoticeble location be? like i said before i want it to look as original as possible.
thanks for your time.

Answer
In the dash will be the least invasive.
Something like this USB shaft mount headunit could be installed seamlessly:

If you do not need USB and only need RCA preouts, try this one:
