Good morning from the Northeast!

Good morning everyone, I am new to the site and very glad to have found a place where there is so much information and knowledge about these cars. I am a new owner of a 73 Dodge Dart Sport 340 and looking forward to asking questions and sharing information. The car shows 48,800 on the odometer and is supposed to be all original minus the 3 speed manual transmission it was built with. How can I find out how many of these cars were built with the 3 speed manual? I was told that this car came out of Florida and that there was a limited number built like this to go around some sort of insurance law in Florida in "73". Thanks for having me on your site.
