1964 Belvedere Rear Seat Belts-

[Scof]

Looking for some pictures of where people have installed the rear seatbelts in their 1964 Plymouth. I’ve seen a few posts, but nothing really clear or definitive. If you have factory seat belts a photo of those with the rear seat removed would be awesome!

I tried to find some photos from my 64 but none was found. Look at your the photo you will find dimples for the location.
If the car was ordered with seat belts they would have been drilled and a reinforcement plate welded under the floor pan.
Mine did. If I knew how I would circle them for you. Alas I am computer illiterate and don't have the skill.
If you look left and right of the hump you can see them. The outer location should be directly across to the outer side of the wheel well.
