1966 -67 bezel can be used in a 64-65 ,but there is a tab which makes it so the bezel can't spin and a very tight fit! A 66-67 antenna can also be used on a 64-65 but the screw in base has to be used and the antenna nut sits higher because of this! If you are not concerned with being 100 percent correct being able to remove the antenna is a nice option! ( unbolts quickly)
