I agree that any seat belt is better than nothing in some cases. just saying don't be disillusioned into thinking that you will be as safe as in a newer vehicle by adding them. go watch some of the crash test of older vehicles on the internet. not sure if they will help all that much in a high speed crash. I will probably be adding the seats with the built in shoulder belt to mine sooner or later. but that is just for my own peace of mine. if you are trying to keep the original seats I really don't know what to tell you.
