Bench with fold down armrest?

I Have A Split Bench Seat With Fold Down Armrest And Adjustable Headrests That I Took Out Of A 72 Dart. I've Removed Cover From Bottom Bench As I Was Going To Recover The Seat But Stopped Cause I Finally Found The Seat I Really Wanted For My Car. The Backs Are Still Covered, The Frame And Springs Are Like Brand New Still Gloss Black No Rust At All. One Headrest Has A Wear Spot On One Side. I All So Have Two 7" Built In Headrest Backs For A Split Bench Seat With No Armrest.
