Seats/Seat belts for daily driver

Hey everyone. So I have a 1967 Dodge Dart GT hardtop 318/A904 that I’m fixing up to be my daily driver. This is my first Mopar, but not my first muscle car. Originally I was planning on redoing my completely worn out low back buckets with new foam/covers from Legendary. My only concerns are the lack of a head rest (impossible to find for ‘67) and the two point seat belt for a daily driver. Now I’m trying to consider all options, so long as I can maintain that vintage muscle car look/feel.

Should I consider some type of after market/other year high back seat? A 3 point belt conversion? Keep it stock? Thanks!
