Seat mods for a more comfortable ride?

I just replaced mine with a more modern bucket seat, not sure how much you can really do to make the bench better. My problem with the bench is I always felt like every time I went around a corner I had to brace myself against the floor with my feet to keep from sliding around on the bench. Way happier now
I would like to replace the bench in my 67 Barracuda with buckets. What seats did you use? Did you have to fab up new seat mounts?
