1972 Heater Bezel Question

I have been looking for a heater/radio dash bezel for my Dart after changing from a/c to non-a/c and wondering if the 1972 bezel is a one year only style or are there other years that will interchange with it as it seems the "'72's" are a harder part to find for sale? Looks nearly identical to the "73-76" style years I am seeing and was wondering what the differences are?

Thanks.
