Thanks to all for the kind words about my car! She (her name is Mary, named after the boys mom and my grandmother) is very dear to my family and we have a ton of fun in her.
Mary has a 327 engine and a 350 turbo transmission in her. She also has duel exhaust with FlowMaster mufflers (which makes her sound pretty damn close to Dean's). Mary also has factory Air Conditioning like Dean's, which will come in nice this summer. The BEST thing about Mary is that she has NO RUST in her as she is one SUPER FINE MACHINE.
As where to get parts for a 67 Impala, I would say the best place is Ebay or a junk yard. Classic Industries is also a good place to find some parts but I as you will find out they do not make that many parts for a 67 Impala and even less for a 4dr hardtop and YES there is a difference between the cars as a 4dr hardtop stands by it's self.
I was think of doing a post on here about my car and ALL of the CORRECT props that I have for her but I didn't know if this would go over very big as I know this is not a car site BUT she is a one of the biggest movie props I have ever owned except for my American Graffiti Coupe and she is WAY BIGGER than the coupe. :lol
