1971 B Body Bucket Seats Rebuilding - Do I need/want these???

[71SandbugCharger]

Hello,
I'm rebuilding my '71 Charger bucket seats, and YearOne has these. Granted my car is missing parts, some are broken and so on, but would I use these for my bucket seats, or are they for bench seats?????

Thanks!!!!

I just did my '72 bucket seats which has bumpers made of steel with a spring. I suppose those nylon substitutes would work, but I prefer the factory metal style.
