I need help with a 1965 Dodge Dart 270

Any help you can provide on a service manual for a 1965 Dodge dart would be greatly appreciated. I have had this car since I was 16, 1994. I drove it for a year and it developed an oil leak so it has sat for nearly 25 years. Now it's time to get her up and running again so any and all help you can send my way as far as where to find parts, a service manual, and any other info would be amazing!
Thanks in advance
John
