OEM Radio question...all of you Duster-Demon-Dart

AdamR....
thanks for the quick answer. But I think I stated the question wrong. I am looking at buying a '71 Demon with an aftermarket radio. I would rather go with a radio delete than an aftermarket. So, I am looking for a stock ''71 radio for a Demon and I would think a '72 would do the job also. But what others would fit?
