looking to put some seat belts in my car, and wanted to go with some 5-point harnesses, but unsure where to mount them, as i do not have a cage in my car. do they just bolt to the floor? any help would be great. thanks.

If your shoulder belts are bolted to the floor and you hit something in the front, your body swings forward and the belt compress your spine instead of holding you back. Bad idea going to the floor, they need to be supported from shoulder height or higher.
