Are '71 and '72 grilles identical?

[jos51700]

I've always wondered this. If not, how do you tell them apart?

Also, if anyone has a picture of a Dart and/or Demon/Duster with a '68-69 'Cuda front clip, could you post pics?

Thanks

Scroll down a few threads on this column, there is a thread with a poll on it that has perfect pics of both.
