Do '55-'65 armrests fit 1966?

[Rust-O-Matic]

I am picking up some new armrests for my '66 on my lunch break today and would like to use the better looking older style arm rests. Classic Parts lists the older style for '55-'65 models, and the cheesy newer style (like mine originally came with) for '66-68.

Since the door panels (including mounting holes) appear to be identical from '64 to '66, I presume the older armrests would bolt right up. Can anyone verify that for certain? I don't wanna spend extra money on rests that won't even fit.
