Plymouth Instrument Cluster 1964 vs. 1965

So is it just the outer bezel shape that is off?

Lets say I grew a wild hair up my tailpipe and I made a mold of the 64 and 65 bezel. Cast them both in plastic and grafted the inner on the 65 into the outer of the 64, smoothed the ribs all even and pretty like... everything is peachy?
