72 Demon Front Bench Seat

Photo of the bench seat in my ‘72 Demon. I have never been convinced that is actually a ‘72 Demon seat as the previous owner mixed several things on this car.
I hope that this helps.

Sorry ,could not get photo to attach, but my measurement similar to your photo was 8 inches.

I found this one here 1972 Plymouth Duster in Greensboro, North Carolina
But most have the strip down the side so not sure if it measured the same
