I have just started restoration on my 69 numbers matching road runner. It's f8 green, vinyl top, 383 , 727 trans. I'm planning to change it to a 4 speed and possibly change color of the car. I know a lot of people are picky about all the numbers matching. I'm not restoring to sell. But I'm still having a hard time deciding if it's a terrible idea to change the car. I know modifying will lower the value. But I don't know if this model would be a big dollar car anyway. Any thoughts that may help me decide?
