I too have a '59 Dodge Coronet.  I've owned it for 5 years.  It has a 326 engine and I converted it to dual exhaust with glasspack mufflers.  I'm trying to make it a "mild custom".  I have changed the taillights to '59 Cadillac lenses, added twin lake pipes and twin dummy spotlights.  It runs great and sure turns a lot of heads when I cruise around in it...

Good luck with your cars...  Gotta love those '59 Dodges..!!
