3 Point Belts??

The lap belt in my 69 Dart vert and an abrupt stop the other day makes me realize how much I like my front teeth.
I know some people use the Sebring seats but I prefer the stock/old school look.
Still looking/researching to modify a better restraint option.
Was lookin at my buddys 87 Camaro vert the other day trying to get ideas... hopefully we can come up with a viable plan.

Was looking into the 3 point belts in the back seat for my son... but alot of the info shows they can be more unsafe than lap belt if not properly installed. Will try to find thread.
