1965 Dart GT "Charger 273"

Hi 65dartcharger, Is it you who is maintaining a registry of A bodies? I am new to the site and love the enthusiasm. I inherited my parent's Charger Dart. Yes, One owner. I remember I was 5 years old, riding in the back and trying to hold between the bucket seats when my Dad punched it. Caught me off guard so I went a flyin'. I guess that's when I got hooked on Muscle Cars. Wondering where my VIN stands with respect to earliest build. L455143471. Thank you, ChargerKG
