Chevrolet: 1975 CHEVY IMPALA SEATBELTS AND NOT STARTING, 1975 chevy impala, chevy impala

Question
Iam driving a 1975 Chevy Impala and everytime you get in if you don't have the seatbelt buckled, the car wont start, this is a problem because the seatbelts aren't able to plug in so I have dummy belts that I shove in and jam between whatever I can. Is there a sensor under the seat? Can I disconnect this and still start the car and if it comes loose the buzzer will not stop until it is back in.

Answer
Wendy;
HI  well first off what you are asking me is illegal to do, and the sensor is in the end of the seat belt, you can get a belt extender if you need one.or new belts ,  or do what you are and hope you do not have a accident as your inshurance will not cover the damage due to the seat belt is not working.    ok
