i heard that lap belts can do a lot of damage to you in certain crashes. kind of why they got rid of them. it really comes down to what you feel comfortable with. I'm still thinking about putting the seats in with the built in shoulder belts but would want to weld something under the truck where the seats would attach to make sure they could not come loose. would hate to go through the window with a seat strapped to me. I heard say that even the should strap one can hurt you. the addition of air bags are pretty much the answer but would be impossible to put in the older trucks. geez now I'm not sure which way to go myself.
