Question about 1968 Dart shoulder belts

1968 Dart 270 said
Cool. So it would appear I could add shoulder belts to mine then sometime in the future. I figured Chrysler would have just had the mounting holes on all the roofs in case someone ordered them and for when the mandate took effecf.

I guess you could rub the head liner to make sure that the bolts are indeed there before cutting the fabric to be sure they are there
