correct switch bezels

Mornin'! Over the last many years, I've been accumulating some OEM stuff to get my Demon as close to original as I can. Put an original radio back in and a fader. Also recently got the correct wiring setup for a rear defogger. I realize that the bezels are different years and am trying to verify which is correct for 1972. I my memory is correct, the original fader that came with the car was chrome, like the rear defog I acquired. I'd like to match them either way but would probably prefer the original type though I think the black plastic looks cleaner. Can anyone verify which is original.
