In 25+ years of restoring Mopars I've only ever restored one 1970 Challenger RT/SE and that was back in 1993. I've since done some front suspensions, dash assemblys and other componets for 70 Challengers, but most of the time has been spent on 71 Cudas and 71 Challengers.
I personally wouldn't think there is any difference in the heater controls, but after being involved with this thread I can see I have a lot to learn.
Most recently...based on the above two photos, the front valance on 70 Challengers must have been installed AFTER the fenders got there coating of sound deadener sprayed on, where-as on 71 Cudas the front bumper and valance were in place because the front signal light housing was almost always covered to some degree.
The differences could be endless.
As stated MANY MANY times...only YOUR car can serve as the true example of how it's supposed to be.
