Help please - Need to source seat belts for 64 Valiant

I replaced the 2 seatbelts in the front of my '64 Valiant with belts from SeatbeltPros.com.
I then bought 2 more for the back seat which didn't have any belts at the time that I bought it.

Just checked out the site. Thank you Glenn. Seems very simple. I thought this was going to be a hassle. John
