5 point harness in a car w/o roll cage...How to do it?

Ok Back to answering the Question posted...The answer is no, because you cant mount them properly. In order to mount the belts properly you'll need a cage with a cross bar mounted no lower than 4" below the drivers shoulders and not above. (According to the NHRA rule book) Reason being is if the shoulder strap mounts are too low it will tend to crush your spine in an accident. Not a good thing.

Yes, I was wanting to keep my back seat. Since I have been gone I have been studying up on cages and paying attention to how other people have done them and I think I am going to make up a cage to put in my car, main hoop on back. Thanks again for everyones input I have definetly learned a great deal! Thanks again!
