Chain and a padlock? I lived in St. Louis in a not very nice area during my college years. I drove a 1970 'Cuda then. Yes, they were just daily drivers in those days, 1978-1982. Batteries in the area were being stolen constantly. Mine never was, though hood had been popped a few times. Slowed the thieves enough that they just moved on. Ran the chain through the latch hook and around the support.
