1969 Dodge Dart Swinger

Hey! So...I am looking for answers on how to locate a car that my Dad used to own in 1970. He was from Rushville, Indiana and bought the car there. He has made several comments over the years about wishing he still had that car. It was Bahama Blue(?) I believe with a black vynil top. It had the 340 Police Interceptor and was and automatic. I would like to find this car for him and purchase it if it's for sale. I have nothing to go on though. No vin # or anything. Can anyone help by steering me in the right direction? Any info would be awesome :) If anyone want to call or text my cell is 269-625-8217 and my name is Justin. Thanks!
