Does a 70 Challenger grille fit a 71?

[cuda2002]

I am sure this question must have been asked before but I can't seem to find anything when I search.  I just got a new project, a 71 Challenger convertible ...... in pieces.  My question is a 70 challenger grille a direct bolt in for a 71?  If not what has to change.

Thanks

I'm no expert but it seems they do--see fern's post:
