I have read previous discussions about installing seat belts in a Stepdown. I want to install seat belts on the rear seat so I can ride my grandkids around in my 49 Super Six coupe, which will require three sets. My question is for those guys that have already installed belts in the back seat, did you use retractable two-point belts or just plain adjustable belts. Like Richard D., I don't see the point in installing 3-point belts in the rear. I eventually want to install three point belts in the front, but that's for later.
