Hey ESchroeder1!
About the 67 pink notch with the shaker hood - Man I love that car! Not so much the color, but the way the whole car was put together. The stance, the shaker hood, the wheel/tire combo, ect.
So here is what I know about the car:
1) The car was built by some guy out east - I think from Pa.
2) He ran into hard times and had to sell the car to a dealer in Pa.
3) The dealer sold the car to a couple in Northern Ill. It is the wife's car.
4) The lady's name is Marie Dixon. I know this because today I googled "pink barracuda" and found that she has pictures of it posted on a site called Car Gurus:

5) The couple tried to buy a car from a friend. He is looking for their phone number which I will PM you if he can find it.
She may be able to get you in contact with the original builder.
