The header panel on my '71 GTX is basically pooched and will need replacing. Are the '71 and '72 panels identical, or are there little differences (typical with Mopars)?

Thanks!

I have one listed in the parts for sale section listed under upper valance (momentary brain lapse). It is straight and rust free. 71 and 72 are the same part except for the emblem.
