1963 Dart seat belt length

[Mineallmine]

Looking for info on the correct lengths for front and rear seat belts for a 63 Dart 2 door sedan. I have the factory holes for the fronts but will have to drill for the rears.

I am planning on getting the aftermarket belts but they come in different lengths. Any info on the correct length for front and rear would be appreciated.

Still looking for the correct lengths. Also, I noticed the seat belts listed for the 64-66 darts look different. Am I correct that the seat belt bolt holes on a 64 are on the side of the transmission tunnel as well as the side of the door/rocker opening? On my 63 they are flat on the floor and won't work with the style I have seen on line listed for the 64.

Should mine be the eye bolt anchor design? Thanks
