Front Seats with head rests....Bench or bucket for early A?

[gdizzle]

on my 66 dart 270 sedan, it has the original Bench seats. I am trying to get it set up for safety for my son. I am working on a 3pt seatbelt, and I would also feel more comfortable with a seat with a headrest, so you dont break your neck. Is there a later model that used a bench with headrests? That might swap right into my car? Or is there a bucket seat option that would swap in easy?

Any help is greatly appreciated. thanks in advance.
pictures would help if you have any.

Sebring buckets with integrated seatbelts have went into a few 2nd generation a-bodies with little effort. There will be more effort/ fabrication req'd in that early a floor pan with any alternate seat you choose. So... Whatever seats you like that fit between the doors. Then look at something like the aluminum super stock seat brackets or fabricate you own. Just make sure they are well secured to the floor.
