Is placing a 72 tail light panel on a 73 blasphemy?

I can help you out with whichever way (or both) that you want to go...
I have a '74 or'75 parts car where the center section of the tail panel is in good shape.
If you go with a new '72 repop tail panel, you will need the inner brackets that the tail lights fasten to. I have an extra set.

I also like the looks of the '70-'72 tail lights better but it would be a bigger task to do that change.
