Here's the year by year differences (USA versions, Canadian may have been different):
The 63 bezel had round buttons and with little punched squares in the background. There was an early version that was chrome plated pot metal, and a later version that was vacuum chromed plastic.
Here's the pot metal version in my 63 Valiant:

Here is the plastic 63 bezel (with very faded chrome):

The 64 bezel was similar to the 63 with the main difference being the horizontal ridges in the background. This one sold here on FABO last year:

The 65 version went to square (or actually, rectangular) buttons, and the base was wider than the top. Still had the horizontal ridges.

66 Barracuda and (I think Valiant) lost the ridges and squared off the perimeter. This is a picture of a restored bezel on the gcartrim.com web site. If you have a decent 64 bezel, he will restore yours for $65.
