Modern seats in a 67 barracuda
It was not a Mopar, but I did put BMW convertible seats into my 66 Fairlane Convertible that I used to have. They were a little sportier so they didn't have as much cushion on them, but were power and gave me much more headroom since the bottom cushion was not very thick. Also, the rails were completely flat which made fitting them into the car much easier.
