Has anyone noticed how weak the floor boards are? ?On the driver's side I have noticed popping sounds everyone once in a while if I move my left foot up and down, having my foot butted up against the drivers seat and door. ?Yesterday decided to investigate it a little and pushed on the floor pan from the top and bottom. ?The top was a little spongy and replicated the popping. ?Went from underneath and knocked and sounded really strange(very hollow sound). ?Definetely not built like my 83' Monte Carlo SS.
