We had a 72 and the buzzing sound rom under the dash sounds like it might be the "headlamps are still on" warning. The seatbelt buzzer sounds different and is actually part of the horn relay. The headlamp doors do sag after a while. They can be fixed. I have done it but I just can't remember how right now. As for the torsion bars breaking, I doubt that has ever happened except in the minds of people who made a living selling cars not made by Chrysler Corp. My dad sold used cars while in college and they were taught to say that whenever they wanted to sell someone something besides a Chrysler. The bard are adjustable. You can't do some front end repairs without having to adjust them. It just takes a big wrench and it helps to have the car's weight off the wheels. The only real concern is the possability that a major bushing or something like that is bad and causing the sag. Adjusting the torsion bars will bring the car back to the correct height but won't solve that problem if its there. Hopefully someone will have the answer on your headlight doors. Best of luck. ________________________________________________________________ GET INTERNET ACCESS FROM JUNO! Juno offers FREE or PREMIUM Internet access for less! Join Juno today!
